STEC01

Overview

The STEC01 is an integrated programmable 12 mΩ power switch managed by the timer based circuitry. The device has 3 timers designed to interrupt the ground path of a power application after a maximum on-time and inhibits the restart of the platform during a cooling window.

  • Input voltage range from 2.2 to 5 V
  • 12 mΩ typ. N-channel FET RDS(on)
  • 7 A continuous current capability
  • PWM control signal from 4 Hz to 5 kHz, with 30% to 100% duty cycle
  • 30 µA battery supply current
  • 2 programmable timers: T1, T3
  • 1 fixed timer T2
  • Input undervoltage lockout
  • VFQFPN 3x3x0.9 16L, 0.5 mm pitch package
