1200V High-Current Half-Bridge using FAN73912

The project presented here is designed for high-voltage and high-speed driving for MOSFETS and IGBTs that operate up to +1200V. The project consists of a FAN73912 gate driver chip and 2 x IGBTs, DC bus capacitors, current sense resistor for current feedback etc. The advanced input filter of HIN provides protection against short-pulsed input signals caused by noise. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8 V (typical) for VBS=15 V. The UVLO circuit prevents malfunction when VCC and VBS are lower than the specified threshold voltage. R8 is the current sense resistor.

We have tested this board with 1200V/40Amps NGTB40N120FL2WG IGBT. The user may install any other MOSFET or IGBT as per power requirements. The value of resistors R1, R2, R3, R5, and C3 (C4) will depend on MOSFET and IGBT selected. Refer to the datasheet of FAN73912 for more information. Choose DC bus Capacitor C6, C7, C8, C9 as per operating power supply. The FAN73912 Output drivers typically source and sink 2 A and 3 A, respectively. Resistors R4 and R6 are bleeding resistors. D4 power LED for VCC, header connector CN2 for signal inputs.

The bootstrap resistor, RBOOT, must be considered in sizing the bootstrap resistance and the current developed during the initial bootstrap charge. If the resistor is needed in series with the bootstrap diode, verify that VB does not fall below COM (ground). Recommended use is typically 5 – 10 Ohms. That increases the VBS time constant. If the voltage drop of the bootstrap resistor and the diode is too high or the circuit topology does not allow a sufficient charging time, a fast recovery or ultra−fast recovery diode can be used.

Features

  • Floating Channel for Bootstrap Operation to +1200 V
  • Logic Power Supply VDD 3.3V to 15V DC (Range 3V to 20V)

VL53L4CD Time-of-Flight High-Accuracy Proximity Sensor measure from 1 mm up to 1200 mm

Posted on by mixos

STMicroelectronics’ ToF sensor provides very accurate distance measurements from only 1 mm up to 1200 mm

Specifically designed for proximity and short-range measurements, STMicroelectronics’ VL53L4CD provides very accurate distance measurements from only 1 mm up to 1200 mm. A new generation laser emitter with 18° FoV (field-of-view) improves performance under ambient light, with ranging speed up to 100 Hz.

With very low power consumption, thanks to an Autonomous mode with programmable distance threshold, the VL53L4CD is ideal for use in battery-powered devices. Its fully embedded on-chip processing helps reduce design complexity and BOM cost since less powerful and less expensive microcontrollers can be used. Like all ToF sensors based on ST’s FlightSense technology, the VL53L4CD records an absolute distance measurement regardless of the target color and reflectance.

Housed in a miniature reflowable package that integrates a SPAD (single-photon avalanche diode) array, the VL53L4CD achieves excellent performance in various ambient lighting conditions and for a wide range of cover glass materials.

All of ST’s ToF sensors integrate a VCSEL (vertical cavity surface emitting laser). It emits a fully invisible 940 nm IR light that is totally safe for the eyes (Class 1 certification).

Features

  • High-accuracy proximity ranging
  • High-performance proximity sensor
  • From 0 mm to 1200 mm with full FoV
  • Short distance linearity down to 1 mm
  • FoV of 18°
  • Autonomous low power mode with programmable interrupt threshold to wake up the host
  • Fast ranging frequency up to 100 Hz
  • Fully integrated miniature module
  • 940 nm invisible laser emitter (VCSEL) and analog driver
  • Low power microcontroller running advanced digital Firmware
  • 4.4 mm x 2.4 mm x 1 mm size
  • Pin-to-pin compatible with VL53L0X, VL53L1X, VL53L1CB, VL53L3CX, and VL53L4CX
  • Easy integration
  • Reflowable component
  • Single power supply 2v8
  • Can be hidden behind cover glass
  • I²C interface (up to 1 MHz)
  • Full set of C software drivers (Linux compatible) for turnkey ranging
  • Embedded processing for very low memory footprint in the host

Texas Instruments DRV8251 4.1A Brushed DC Motor Driver

Posted on by mixos

Texas Instruments DRV8251 4.1A Brushed DC Motor Driver is an integrated motor driver with N-channel H-bridge, charge pump, current regulation, and protection circuitry. The charge pump improves efficiency by supporting N-channel MOSFET half-bridges and 100% duty cycle driving. The DRV8251 implements a current regulation feature by comparing the analog input VREF and the voltage across a current-sense shunt resistor on the ISEN pin. The ability to limit current can significantly reduce large currents during motor startup and stall conditions.

A low-power sleep mode achieves ultra-low quiescent current draw by shutting down most internal circuitry. Internal protection features include supply undervoltage lockout, output overcurrent, and device overtemperature. The Texas Instruments DRV8251 is part of a family of devices that comes in pin-to-pin, scalable RDS(on), and supply voltage options to support various loads and supply rails with minimal design changes.

Features

Diodes Incorporated AP61300Q/AP61302Q Synchronous Buck Converters

Posted on by mixos

Diodes Incorporated AP61300Q/AP61302Q Synchronous Buck Converters are automotive-compliant, 3A, converters having a wide input voltage range of 2.4V to 5.5V. These devices completely integrate a 70mΩ high-side power MOSFET and a 50mΩ low-side power MOSFET which provides high-efficiency step-down DC-DC conversion. The AP61300Q/AP61302Q buck converters can easily be used by minimizing the external component count as it adopts Constant On-Time (COT) control. The COT control helps in achieving fast transient response, easy loop stabilization, and low output voltage ripple. Applications include automotive power systems, automotive infotainment, automotive instrument clusters, automotive telematics, and Advanced Driver Assistance Systems (ADAS).
