7.4.6 Active Mode

The device transitions from shutdown mode to active mode directly when EN/UVLO and LPM are driven high together at same time.

TPS12130-Q1 transitions from low power mode into active mode by:

  • External Trigger: Drive LPM high externally.
  • Internal Trigger: After load current exceeds load wakeup threshold (ILWU), TPS12130-Q1 automatically turns OFF the bypass FET (G2 gate drive). Drive LPM high after load wakeup event to switch to active mode.

In this mode, charge pump, gate drivers and all protections are enabled. The main FET (G1 gate drive) can be tuned ON or OFF by driving INP high or low respectively and bypass FET (G2 gate drive) is turned OFF and WAKE pin asserts low in this state.

The device exits active mode and enters low power mode when LPM is pulled low.

Protections available in active state are:

  • Input UVLO: Main FET (G1 gate drive) is turned OFF when voltage on EN/UVLO falls below V(UVLOF) and FLT asserts low.
  • Charge pump UVLO: Main FET (G1 gate drive) is turned OFF when voltage between BST to SRC falls below V(BST_UVLOF) and FLT asserts low.
  • Short-circuit protection: Main FET (G1 gate drive) is turned OFF when voltage across CS+ and CS– exceeds the set short-circuit threshold (VSCP/LWU). The device goes in auto-retry or latch-off based on the selected configuration and FLT asserts low.
