VNL5050N3TR-E OMNIFET III Low‑Side Driver
The VNL5050N3TR-E is a fully protected single‑channel low‑side driver manufactured by STMicroelectronics using advanced VIPower® technology, designed for driving resistive, inductive, and capacitive loads in automotive and industrial systems. Housed in a compact SOT‑223 (TO‑261‑4) surface‑mount package, it operates with a supply voltage of 4.5 V to 5.5 V, delivers a maximum continuous drain current of 19 A (27 A peak), and features an ultra‑low 50 mΩ typical RDS(on) at 5 V gate drive, with a 41 V overvoltage clamp for inductive load protection. This monolithic IC integrates a power MOSFET with comprehensive protection circuitry, providing a robust, cost‑effective solution for reliable load switching in harsh environments.
This low‑side driver offers logic‑level input compatibility with 5 V microcontrollers, very low standby current (<10 µA), and minimal electromagnetic susceptibility, ensuring easy integration and high noise immunity. It includes comprehensive fault protection: thermal shutdown with automatic restart, overcurrent and power limitation, short‑circuit protection, and ESD protection, safeguarding the device and load from damage. Fast inductive load demagnetization at turn‑off enhances system reliability, while the −40°C to +150°C operating temperature range and AEC‑Q100 qualification confirm its suitability for automotive applications. Core applications include automotive body electronics (lighting, solenoids, motors), industrial relay and valve drivers, battery‑powered systems, power distribution units, and LED lighting drivers.
