Pin Functions

PIN TYPE(1) DESCRIPTION APPLICATION INFORMATION
NO. NAME
1 VDD P Supply voltage
2 GND G Ground
3 DELAY/ M_DRV I Time interval configuration (during power on) and logic input for manual Power ON Resistance between this pin and GND is used to select the time interval. The manual Power ON signal (logic HIGH) can also connected to this pin.
4 DONE I Logic Input for watchdog functionality Digital signal driven by the µC to indicate successful processing.
5 DRVn O Power Gating output signal generated every tIP The ENABLE pin of the LDO or DC-DC converter is connected to this pin. DRVn is active HIGH.
6 EN/ ONE_SHOT I Select mode of operation When EN/ONE_SHOT = HIGH, the TPL5111 works as a TIMER. When EN/ONE_SHOT = LOW, the TPL5111 asserts DRVn one time for the programmed time interval. In this mode, the DRVn signal may be manually asserted by applying a logic HIGH to the DELAY/M_DRV pin.
(1) G= Ground, P= Power, O= Output, I= Input.
