RDGD31603PSMKEVM three-phase inverter kit

4.2.9 Advanced IGBT gate driver

4.2.9.1 General description

The GD3160 is an advanced single channel gate driver for IGBTs. Integrated Galvanic

isolation and low on-resistance drive transistors provide high charging and discharging

current, low dynamic saturation voltage, and rail-to-rail gate voltage control.
Current and temperature sense minimizes IGBT stress during faults. Accurate and

configurable under voltage lockout (UVLO) provides protection while ensuring sufficient

gate drive voltage headroom.
The GD3160 autonomously manages severe faults and reports faults and status via the

INTB pin and a SPI interface. It is capable of directly driving gates of most IGBTs. Self-

test, control, and protection functions are included for design of high reliability systems

(ASIL C/D). It meets the stringent requirements of automotive applications and is fully

AEC-Q100 grade 1 qualified.

4.2.9.2 GD3160 features

•

Compatible with current sense and temp sense IGBTs

•

Fast short circuit protection for IGBT/SiC with DESAT and current sense feedback

•

Compliant with ASIL D ISO 26262 functional safety requirements

•

SPI interface for safety monitoring, programmability, and flexibility

•

Integrated Galvanic signal isolation

•

Integrated gate drive power stage capable of 15 A peak source and sink

•

Interrupt pin for fast response to faults

•

Compatible with negative gate supply

•
