DC motor driver able to adapt the external power stage for different electronic applications
The L99H02 is designed to drive 4 external N-channel MOS transistors in H-bridge configuration for DC-motor driving in automotive applications. A free configurable current sense amplifier is integrated. The integrated SPI interface allows to manage the device and provides diagnostic information. An interface pin for the thermal sensors of the external MOSFETs is implemented.
Key features of L99H02
- Embedded thermal sensors with an interface pin for reverse battery protection of external MOSFETs
- Two package options for optimizing either PCB area or power dissipation
- Free SPI-configurable current sense amplifier able to multiplex two shunts
- Programmable thermal, undervoltage, overvoltage and cross-current protections
