UCC5871-Q1 30-A Isolated IGBT/SiC MOSFET Gate Driver with Advanced Protection Features for Automotive Applications
1 Features
- Split output driver provides 30-A peak
source and 30-A peak sink currents
- Interlock and shoot-through protection
with 150-ns(max) propagation delay and programmable minimum pulse rejection
- Primary and
secondary
side active short circuit (ASC) support
- Configurable power transistor protections
- DESAT based short circuit protection
- Shunt resistor based overcurrent and short circuit protection
- NTC based overtemperature protection
- Programmable soft turnoff (STO) and two-level turnoff (2LTOFF)
during power transistor faults
- Functional Safety-Compliant
- Integrated diagnostics:
- Built-in self test (BIST) for protection comparators
- IN+ to transistor gate path integrity
- Power transistor threshold monitoring
- Internal clock monitoring
- Fault alarm (nFLT1) and warning (nFLT2) outputs
- Integrated 4-A active Miller clamp or
optional external drive for Miller clamp transistor
- Advanced high voltage clamping
control
- Internal and external supply undervoltage
and overvoltage protection
- Active output pulldown and default low
outputs with low supply or floating inputs
- Driver die temperature sensing and
overtemperature protection
- 100-kV/µs minimum common mode transient
immunity (CMTI) at VCM = 1000 V
- SPI based device reconfiguration,
verification, supervision, and diagnosis
- Integrated 10-bit ADC for power
transistor temperature, voltage, and current monitoring
