Single-channel high-side driver for inductive and resistive loads
The STMicroelectronics VN5E025MJ-E is a VIPower™ single-channel high-side driver with an N-channel power MOSFET output. Built-in fault protection includes current limiting (fixed threshold), over-temperature shutdown, and over-voltage clamping — no external Vcc supply is required for the logic input, simplifying the BOM. The Auto Restart feature means the driver cycles on/off after a thermal fault, re-trying the load automatically once the junction cools below the reset threshold — useful for lamp inrush or motor stall recovery without software intervention.
25 mOhm Rds(on) and 43 A peak — load headroom for high-surge applications
The 43 A peak output rating handles lamp cold-start inrush, DC motor start-up, and capacitive loads well beyond the steady-state current requirement — but the actual continuous current is thermally limited by the board layout and ambient temperature.
STMicroelectronics no longer manufactures this exact variant in volume; new-production orders are not accepted from the factory. Available inventory is limited to stock already in the distribution channel. Confirm the BOM position and thermal budget before committing; the Auto Restart and fault protection set may not be identical on newer VIPower parts.
PowerSSO-12 footprint and thermal design
The datasheet recommends a minimum copper area on the top layer and via stitching to the ground plane to achieve the rated junction-to-ambient thermal resistance. Derate the continuous output current above the rated junction temperature per the thermal impedance curves in the datasheet.
