SLVSDO6C August 2017 – June 2019 TPS1H000-Q1
PRODUCTION DATA.
When a current limit occurs, the TPS1H000-Q1 device supports three different behaviors of the output.
MODE | DELAY CONFIGURATION | OUTPUT CURRENT BEHAVIOR | FAULT RECOVERY |
---|---|---|---|
Holding | Connect to GND directly | When hitting a current limit, the output current holds at the setting current. The device enters into thermal shutdown mode when TJ > T(SD). |
FAULT clears when IN turns low for a duration longer than tFAULT OR when the current limit is removed when IN is high. |
Latch-off | Connect to GND through a capacitor | When hitting a current limit, the output current holds at the setting current, but latches off after a preset DELAY time (tdl1+ tdl2). tdl1 is the default delay time; tdl2 is a capacitor-configurable delay time.
The output stays latched off regardless of whether the current limit is removed. The output recovers only when IN is toggling. |
FAULT clears when IN turns low for a duration longer than tFAULT. |
Auto-retry | External pullup | When hitting a current limit, the output current holds at the setting current, but periodically comes on for thic(on) and turns off for thic(off). |
FAULT clears when IN turns low for a duration longer than tFAULT OR when the current limit is removed for thic(on) |
