PRODUCTION DATA
The VOUT_OV_FAULT_RESPONSE instructs the device on what action to take in response to an output overvoltage fault. The VOUT_OV_FAULT_RESPONSE command must be accessed through Read Byte transactions. The VOUT_OV_FAULT_RESPONSE command is shared between Channel A and Channel B. All transactions to this command affects both channels regardless of the PAGE command.
Upon triggering the over-voltage fault, the device is latched off, and:
| 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| R | R | R | R | R | R | R | R |
| VO_OV_RESP | |||||||
| LEGEND: R/W = Read/Write; R = Read only |
| Bit | Field | Type | Reset | Description |
|---|---|---|---|---|
| 7:0 | VO_OV_RESP | R | 80h | 80h: Latch-off and do not restart. To clear a shutdown event due to a fault event, the user must toggle the AVR_EN/BEN pin and/or the ON bit in OPERATION, per the settings in ON_OFF_CONFIG, or power cycle the bias power to the V3P3 pin of the controller device. |
