4.1.10 USB LDO Short-Circuit Protection Scheme
The short-circuit current for the LDOs and dc-dcs in the TPS65920 and TPS65930 devices is
approximately twice the maximum load current. When the output of the block is shorted to ground, the
power dissipation can exceed the 1.2-W requirement if no action is taken. A short-circuit protection
scheme is included in the TPS65920 and TPS65930 devices to ensure that if the output of an LDO or
dc-dc is short-circuited, the power dissipation does not exceed the 1.2-W level.
The three USB LDOs, VRUSB3V1, VRUSB1V8, and VRUSB1V5, are included in this short-circuit
protection scheme, which monitors the LDO output voltage at a frequency of 1 Hz and generates an
interrupt (sc_it) when a short-circuit is detected.
The scheme compares the LDO output voltage to a reference voltage and detects a short-circuit if the
LDO voltage drops below this reference value (0.5 or 0.75 V programmable). In the case of the
VRUSB3V1 and VRUSB1V8 LDOs, the reference is compared with a divided down voltage (1.5 V typical).
If a short-circuit is detected on VRUSB3V1, the power subchip FSM switches this LDO to sleep mode.
If a short-circuit is detected on VRUSB1V8 or VRUSB1V5, the power subchip FSM switches off the
relevant LDO.
