It is part of a larger family offering half-bridge drivers from three outputs to twelve outputs with direct interface or SPI interface. The half bridge drivers are designed to drive DC motor loads in sequential or parallel operation. Operation modes forward (cw), reverse (ccw), brake and high impedance are controlled from a 16-bit SPI interface. It offers diagnosis features such as short circuit, open load, power supply failure and overtemperature detection. In combination with its low quiescent current, this device is attractive among others for automotive applications. The small fine pitch exposed pad package, PG-TSDSO-14, provides good thermal performance and reduces PCB-board space and costs.
Summary of Features
Four half bridge power outputs
Very low power consumption in sleep mode
3.3V / 5V compatible inputs with hysteresis
All outputs with overload and short circuit protection
Independently diagnosable outputs (overcurrent, open load)
Open load diagnostics in ON-state for all high-side and low-side
16-bit Standard SPI interface with daisy chain and in-frame response capability for control and diagnosis
Fast diagnosis with the global error flag
Overtemperature pre-warning and protection
Over- and Undervoltage lockout
Cross-current protection
Potential Applications
HVAC Flap DC motors
Monostable and bistable Relays
Side mirror x-y adjustment and mirror fold
Applications
Automotive body control module (BCM)
Body electronics and power distribution
HVAC control module
Multi-port fuel injection
Small 1-cylinder combustion engine solution
