TPS51117

DETAILED DESCRIPTION (continued)

UVLO PROTECTION

The TPS51117 has V5FILT undervoltage lockout protection (UVLO). When the V5FILT voltage is lower than the

UVLO threshold voltage, the TPS51117 is shut off. This is a nonlatched protection.

THERMAL SHUTDOWN

The TPS51117 monitors the temperature of itself. If the temperature exceeds the threshold value (typically

160°C), the TPS51117 shuts itself off. Both top and bottom gate drivers are tied low with output discharged

through the VOUT terminal. This is also a nonlatched protection. The device recovers once the temperature has

decreased approximately 12°C.
