ZHCSHT5A July 2011 – March 2018 TPS61256A
PRODUCTION DATA.
The TPS61256A device starts operation when EN is set high and starts up with the soft-start sequence. For proper operation, the EN pin must be terminated and must not be left floating.
Pulling the EN pin low forces the device in shutdown, with a shutdown current of typically 1µA. In this mode, true load disconnect between the battery and load prevents current flow from VIN to VOUT, as well as reverse flow from VOUT to VIN.
