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 modulated (PWM) signal as long as the fault is present. These devices provide control of output channels through a serial input interface or a parallel input interface. A mand to enable the output from July 2003 either interface enables the respective channels gate output to the external FET. The serial interface is remended when the number of signals between the control device and the predriver are minimized and the speed of operation is not critical. In applications where the...
