Features
• AEC-Q100 qualified
• 12 V and 24 V battery systems compliance
• 3.3 V and 5 V logic compatible I/O
• 8-channel configurable MOSFET pre-driver
– High-side (N-channel and P-channel MOS)
– Low-side (N-channel MOS)
– H-bridge (up to 2 H-bridge)
– Peak & Hold (2 loads)
• Operating battery supply voltage 3.8 V to 36 V
• Operating VDD supply voltage 4.5 V to 5.5 V
• Programmable gate charge/discharge currents for improving EMI behavior
• Individual diagnosis for:
– Short circuit to battery
– Open load
– Short circuit to ground
• Highly flexible overcurrent sensing implementation
– Possibility of monitoring external MOS drain to source voltage
– Possibility of monitoring voltage on external shunt resistor
– 64 programmable overcurrent thresholds independent for each channel
– Ultra-fast output shutdown in case of overcurrent
• Current limitation for H-Bridge configuration
• 32-bit SPI protocol available for configuration and diagnostics
– Failures latched even if they occur during diagnostics reading
– Daisy chain operation
– SDO protected against overvoltage
• Safety features
– Fast switch off redundant output disable by two external pins
– Built In Self Test (BIST) for logic operation
– Hardware Self Check (HWSC) for VDD5 overvoltage comparator
– Configurable Communication Check (CC) watchdog timer available
– Disable feedback by bi-directional pin
– Highly redundant output monitoring by dedicated SPI registers
• 10-bit ADC for battery and die temperature measurements available by SPI
• VDD5 monitoring for over/under voltage
• VPS (battery) monitoring for under voltage
Applications
• Automotive 12 and 24 V (passenger and commercial vehicles) applications
• Low-side, high-side, Peak and hold and H-Bridge load control
• Designed for driving relays, motors, and all the resistive and inductive loads
