VQN5050K-E is a quad channel high side driver for automotive applications by ST. It has features such as low power consumption, 3.0 V CMOS compatible input, optimized electromagnetic emission and low electromagnetic susceptibility.
The VNQ5050K-E is a monolithic quad channel high side driver designed for automotive applications using STMicroelectronics VIPower MOS-5 technology. It is intended for driving resistive or inductive loads with one side connected to ground and includes active VCC pin voltage clamp protection against low energy spikes.
The device features diagnostic functions such as open drain status output, on-state and off-state open load detection, and thermal shutdown indication. It offers comprehensive protection including undervoltage shutdown, overvoltage clamp, load current limitation, and protection against loss of ground or VCC.
