4-channel automotive high-side driver supports 12 V ground-connected loads

The VNQ9050LAJ from STMicroelectronics is a 4-channel automotive high-side driver for 12 V ground-connected loads, operating from a 4 V minimum supply and maintaining functionality during cold cranking down to 2.7 V in compliance with LV124 standards. Built on VIPower™ M09 technology, the device features typical on-resistance of 50 mΩ, compatibility with 3 V and 5 V logic, integrated current-sense diagnostics via an on-chip current mirror and protection functions including overvoltage clamp, thermal shutdown, reverse-battery and short-circuit protection. Housed in a Power-SSO16 package, it targets automotive body and lighting applications requiring load monitoring, fault detection and robust transient performance.
