Single-channel high-side switch with integrated fault protection
The VN5E160STR-E is a single N-channel high-side power switch from STMicroelectronics' VIPower™ family, designed for general-purpose switched loads up to 7 A continuous. Input control is a simple On/Off logic pin with non-inverting polarity — no external Vcc supply needed, which simplifies the interface to a GPIO or switch. The 1:1 input-to-output ratio means one control line drives one load channel.
Fault protection suite — current limiting, open load, over-temp, over-voltage
This eliminates external sense resistors, comparators, and TVS diodes for many applications — the BOM saves a handful of passives per channel. The Auto Restart feature means the switch automatically re-tries after an over-temperature fault once the die cools, which is useful for intermittent overloads like lamp inrush or motor stall. For latched-off designs, the TDE1747FPT peer offers adjustable current limiting but lacks Auto Restart and has a narrower load voltage range (10 V max) and lower operating temperature ceiling (85 °C).
Active production — no end-of-life risk for committed BOMs
Procurement can commit to multi-year builds without a last-time-buy window. The 8-SOIC package is a standard footprint with 0.154-inch body width, compatible with common reflow profiles.
