SLVSFE3B November 2020 – May 2021 TPS2661
The TPS2661x provides an indication of the current signal flowing through pass FETs on the SGOOD pin. Whenever the device is in normal operating condition, the SGOOD gives a signal LOW output. However in below cases when the device is outside normal operating condition, the SGOOD pin goes HIGH:
The SGOOD pin is also capable of driving an external LED to give a visual indication whenever the system is outside normal operating conditions.
The SGOOD pin sourcing current is derived from +Vs supply rail. For de-glitch delays in assertion and de-assertion of SGOOD, see TSG_Deglitch in Timing Requirements in Specifications.
