The VNQ5027AK-E is a quad channel high side driver with analog current sense for automotive applications. It features an output current of 42A, 3.0V CMOS compatible input, current sense disable, proportional load current sense, undervoltage shut-down, overvoltage clamp, thermal shutdown, current and power limitation, very low standby current, protection against loss of ground and loss of VCC, very low electromagnetic susceptibility, optimized electromagnetic emission, and reverse battery protection.
The VNQ5027AK-E is a monolithic device utilizing STMicroelectronics VIPower technology. It functions as a four-channel high-side switch intended to drive resistive or inductive loads where one side connects to ground. The device features an integrated analog current sense function that provides a signal proportional to the load current when enabled, alongside comprehensive protection mechanisms including undervoltage shut-down, overvoltage clamping, and thermal shutdown.
