The TPS65058 contains a monitor circuitry that monitors the outputs of the DCDC converters and applies a reset
pulse to the RESET pin. As soon as the supply voltage on the VCC pin is above the undervoltage lockout
threshold, the RESET pin is pulled low. After the enabling of both DCDC converters, the output voltages are
monitored. When both outputs are within 95% of the desired output voltage, the reset timer is started and after a
delay of 100ms the Reset output is switched to high impedance. If one of the output voltages is outside of the
regulation band (90% of the desired value) the RESET pin remains to be pulled to ground. After both outputs are
back in regulation, the 100ms timer is started, and after 100ms the RESET output is again switched to high
impedance.
Figure 19. RESET Pulse Circuit
All outputs are short circuit protected with a maximum output current as defined in the Electrical Characteristics.
As soon as the junction temperature, TJ, exceeds typically 150°C for the DCDC converters, the device goes into
thermal shutdown. In this mode, the P and N-Channel MOSFETs are turned-off. The device continues its
operation when the junction temperature falls below the thermal shutdown hysteresis again. A thermal shutdown
for one of the DCDC converters will disable both converters simultaneously.
