Figure 21. 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.
The thermal shutdown temperature for the LDOs are set to typically 140°C. Therefore a LDO which may be used
to power an external voltage will never heat up the chip high enough to turn off the DCDC converters. If one LDO
exceeds the thermal shutdown temperature, all LDOs will turn off simultaneously.
The low dropout voltage regulators are designed to be stable with low value ceramic input and output capacitors.
They operate with input voltages down to 1.5V. The LDOs offer a maximum dropout voltage of 280mV at rated
output current. Each LDO supports a current limit feature. The LDOs are enabled by the EN_LDO1, EN_LDO2,
and EN_LDO3 pin. The output voltage of LDO1 and LDO2 is set using an external resistor divider whereas
LDO3 has a fixed output voltage of 1.30 V for TPS65053, 1.20V for TPS650531 and 1.50V for TPS650532.
