N/A [7:5] Reserved
SHORT_INT 4 Short-circuit error interrupt.
1 = a short-circuit or overload condition on VOUT has been detected.
0 = no short-circuit or overload condition has been detected.
TSD_INT 3 Thermal shutdown interrupt.
1 = the device temperature has exceeded 150°C (typical).
0 = no overtemperature condition has been detected.
OVP_INT 2 Overvoltage interrupt.
1 = VOUT has exceeded V

0 = VOUT has not exceeded V

Interrupt bits are cleared by writing a 1 to the flag; writing a 0 or reading the flag has no effect.

SHORT_IEN 4
Short-circuit interrupt is enabled. When the SHORT_INT status bit is set after an error condition, an interrupt is
raised to the host if the SHORT_IEN flag is enabled.
1 = the short-circuit interrupt is enabled.
0 = the short-circuit interrupt is disabled (the SHORT_INT flag continues to assert).
TSD_IEN 3
Thermal shutdown interrupt is enabled. When the TSD_INT status bit is set after an error condition, an interrupt is
raised to the host if the TSD_IEN flag is enabled.
1 = the thermal shutdown interrupt is enabled.
0 = the thermal shutdown interrupt is disabled (the TSD_INT flag continues to assert).
OVP_IEN 2
Overvoltage interrupt enabled. When the OVP_INT status bit is set after an error condition, an interrupt is raised to
the host if the OVP_IEN flag is enabled.
1 = the overvoltage interrupt is enabled.
0 = the overvoltage interrupt is disabled (the OVP_INT flag continues to assert).
N/A [1:0] Reserved.
