SLVSDY6A – AUGUST 2018 – REVISED JUNE 2019
DRV835x 100-V Three-Phase Smart Gate Driver
1 Features
1 9 to 100-V, Triple half-bridge gate driver – Optional integrated buck
regulator – Optional triple low-side current shunt amplifiers
Smart gate drive architecture – Adjustable slew rate control for EMI performance – VGS handshake and minimum dead-time insertion to prevent shoot-through – 50-mA to 1-A peak source current – 100-mA to 2-A peak sink current – dV/dt mitigation through strong pulldown
Integrated gate driver power supplies – High-side doubler charge pump For 100% PWM duty cycle control – Low-side linear
regulator
Integrated LM5008A buck
regulator – 6 to 95-V operating voltage range – 2.5 to 75-V, 350-mA output capability
Integrated triple current shunt amplifiers – Adjustable gain (5, 10, 20, 40 V/V) – Bidirectional or unidirectional support
6x, 3x, 1x, and independent PWM modes – Supports 120° sensored operation
SPI or hardware interface available Low-power sleep mode (20 µA at VVM = 48-V) Integrated protection features
– VM undervoltage lockout (UVLO) – Gate drive supply undervoltage (GDUV) – MOSFET VDS overcurrent protection (OCP) – MOSFET shoot-through prevention – Gate driver fault (GDF) – Thermal warning and shutdown (OTW/OTSD) – Fault condition indicator (nFAULT)
