VN5012AK-E

Power Distribution Switches, Load Drivers Overview

The VN5012AK-E is a single-channel high-side switch from STMicroelectronics, built on VIPower M0-5 technology. It drives resistive or inductive loads with one side grounded. Key electrical parameters include a load voltage range of 4.5V to 36V and a maximum output current of 45A. The typical on-resistance is 12 milliohms. It operates within a junction temperature range of -40°C to 150°C. The device features an analog current sense pin proportional to load current, which can be disabled via the CS_DIS input. Integrated protections include undervoltage shutdown, overvoltage clamp, load current limitation, thermal shutdown with automatic restart, reverse battery protection, and ESD protection.
