ZHCSE52B September 2015 – May 2019 TPS57140-EP
PRODUCTION DATA.
The TPS57140-EP has an overload recovery (OLR) circuit. The OLR circuit slow-starts the output from the overload voltage to the nominal regulation voltage on removal of the fault condition. The OLR circuit discharges the SS/TR pin to a voltage slightly greater than the VSENSE pin voltage using an internal pulldown of 100 μA when the error amplifier is changed to a high voltage from a fault condition. On removal of the fault condition, the output slow-starts from the fault voltage to the nominal output voltage.
