INFINEON AUIR3314S High Side Switch
The AUIR3314S is a fully protected high-side switch with four terminals, designed for automotive power management applications. Its input signal is referenced to Vcc, and the device turns on the output power MOSFET when the voltage difference (Vcc - Vin) exceeds a specified threshold. Conversely, it turns off the MOSFET when the voltage difference falls below a set input voltage level. The switch features current sensing on the feedback pin (Ifb), and overcurrent shutdown occurs when Vifb - Vin exceeds 4.7 V. This threshold can be adjusted by selecting the appropriate sensing resistor. The device also includes protections such as short-circuit protection, reverse battery protection, active clamp, ESD, and reverse battery protection, making it durable for automotive environments. The design incorporates active gate control for reduced electromagnetic interference (EMI), programmable overcurrent shutdown, and a bootstrap regulator with a charge pump. The switch is reset by pulling the input pin high after a fault condition.
