Single-channel high-side driver in PowerSSO-12
The STMicroelectronics VN5E050JTR-E is a single-channel high-side driver from the VIPower™ family, built around an N-channel MOSFET output with a 1:1 input-to-output ratio. It switches a load referenced to ground, with the output sourcing current from the battery rail.
Maximum on-resistance of 50 mOhm sets the resistive loss at rated current: at 19 A, the VDS drop is under 0.95 V, keeping the die temperature rise manageable even in a 150°C junction environment.
The On/Off interface with a non-inverting input simplifies direct connection to a microcontroller GPIO or a PWM timer — no level-shift or external driver stage needed.
