Product Details
STEC01PUR - Programmable Ground-Path Safety Switch
STEC01PUR from STMicroelectronics is a programmable low-resistance ground-path safety switch for power tools and battery systems in a 3 mm x 3 mm VFQFPN-16 package.
Specifications were checked against the manufacturer data sheet and current distributor listing.
Overview
STEC01 integrates a low-resistance N-channel MOSFET, control logic and programmable timers to disconnect the load ground path after abnormal or excessive activation time.
Key Advantages
A 12 milliohm typical integrated power switch supports continuous currents up to 7 A with low conduction loss.
Programmable on-time and cooling-window supervision adds an independent safety layer for trigger-driven loads.
Available in an established surface-mount or through-hole ordering format.
Electrical and environmental limits are defined by the official data sheet.
Feature Summary
Programmable power-ground safety switch with timing protection
Trigger and PWM-compatible control inputs with timer-programming components and diagnostic state
2.2 V to 5 V supply; up to 7 A continuous; 4 Hz to 5 kHz PWM; VFQFPN-16 3 mm x 3 mm
16-VFQFN Exposed Pad
Package & Footprint
This ordering code uses the 16-VFQFN Exposed Pad package.
Pin Functions
Confirm exact numbering and the latest land pattern before PCB release.
