14 / 22 page Thermal Shutdown Power Good (PWRGD) TPS54617 SLVS880A – NOVEMBER 2008 – REVISED JANUARY 2009 ........................................................................................................................................... www.ti.com The device uses the thermal shutdown to turn off the The power good circuit monitors for under voltage power MOSFETs and disable the controller if the conditions on VSENSE. If the voltage on VSENSE is junction temperature exceeds 150°C. The device is 10% below the reference voltage, the open-drain released from shutdown automatically when the PWRGD output is pulled low. PWRGD is also pulled junction temperature decreases to 10°C below the low if VIN is less than the UVLO threshold or SS/ENA thermal shutdown trip point, and starts up under is low. When VIN ≥ UVLO threshold, SS/ENA ≥ control of the slow-start circuit. enable threshold, and VSENSE > 90% of Vref, the open drain output of the PWRGD pin is high. A Thermal shutdown provides protection when an hysteresis voltage equal to 3% of Vref and a 35 µs overload condition is sustained for several falling edge deglitch circuit prevent tripping of the milliseconds. With a persistent fault condition, the power good comparator due to high frequency noise. device cycles continuously; starting up by control of the soft-start circuit, heating up due to the fault condition, and then shutting down upon reaching the thermal shutdown trip point. This sequence repeats until the fault condition is removed. 14 Submit Documentation Feedback Copyright © 2008–2009, Texas Instruments Incorporated Product Folder Link(s) :TPS54617 |
