Description
Reserved.
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).
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).
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).
When the CMP2_INT status bit is set after an enabled comparator trips, an interrupt is raised if the CMP2_IEN flag is
enabled.
1 = the second phototransistor comparator interrupt is enabled.
0 = the second phototransistor comparator interrupt is disabled (the CMP2_INT flag continues to assert).
Bit 5
Bit 5
Description
Reserved.
Short-circuit error.
1 = a short-circuit or overload condition on VOUT was detected.
0 = no short-circuit or overload condition has been detected.
Thermal shutdown.
1 = the device temperature has exceeded 150°C (typical).
0 = no overtemperature condition has been detected.
Overvoltage interrupt.
1 = VOUT has exceeded V
0 = VOUT has not exceeded V
1 = indicates that the second ALS comparator (CMP_IN2) has changed state.
0 = the second sensor comparator has not triggered.
1 = indicates that the main ALS comparator (CMP_IN) has changed state.
0 = the main sensor comparator has not triggered.
