Over/Under Voltage Protection
The TPS54429E detects over and undervoltage conditions by monitoring the feedback voltage (VFB). This
function is enabled after approximately 1.7 times the soft-start time. When the feedback voltage becomes higher
than 120% of the target voltage, the OVP comparator output goes high and the circuit latches the high-side
MOSFET driver turns off and the low-side MOSFET turns on. When the feedback voltage becomes lower than
65% of the target voltage, the UVP comparator output goes high and an internal UVP delay counter begins. After
250 s, the device latches off both internal top and bottom MOSFET.
UVLO Protection
Undervoltage lock out protection (UVLO) monitors the voltage of the VREG5 pin. When the VREG5 voltage is lower
than UVLO threshold voltage, the TPS54429E is shut off. This is protection is non-latching.
Thermal Shutdown
Thermal protection is self-activating. If the junction temperature exceeds the threshold value (typically 165°C),
the TPS54429E shuts off. This protection is non-latching.
