It is mainly designed to provide low-frequency switching, inductive load applications such as solenoids and relays. Fault status is available in a serial-data format. Each driver channel has independent off-state open-load detection and on-state shorted load short to battery detection. The STPIC44L02 offers a battery over voltage and undervoltage detection and shutdown. If a fault occurs while using the STPIC44L02, the channel transitates into a low duty cycle, pulse width ...
