VOUT_UV_FAULT_RESPONSE

The VOUT_UV_FAULT_RESPONSE command determines the fault response for the VOUT_UV_FAULT flag.

Bits

Bit Name/Function

R/W

Description

[7:6]

Response

R/W

00 = continues operation without interruption.

01 = continues operation for the Delay Time 1 (Bits[2:0]). If the fault persists, retry the number of

times specified by the retry setting (Bits[5:3]).

10 = shuts down (disables the output) and responds according to the retry setting in Bits[5:3].

11 = the output is disabled while the fault is present. Operation resumes and the output is enabled

when the fault condition no longer exists.

[5:3]

Retry setting

R/W

000 = restart not attempted. The output remains disabled until the fault is cleared.

001 to 110 = attempts to restart the number of times set by these bits. If the unit fails to restart in

the allowed number of retries, it disables the output and remains off until the fault is cleared. The time

between the start of each attempt to restart is set by the Delay Time 2 value in Bits[2:0], together

with the delay time unit specified for that particular fault.

111 = attempts to restart continuously, without limitation, until it is commanded off (by the CTRL pin

or the OPERATION command, or both), VDD is removed, or another fault condition causes the unit to

shut down.

[2:0]

Delay time

R/W

These bits set the delay time for the VOUT_UV_FAULT_RESPONSE Delay Time 1 and Delay Time 2 as

described in Bits[7:6] and Bits[5:3].

OT_FAULT_LIMIT

The OT_FAULT_LIMIT command sets the threshold value in degrees Celsius (°C) for overtemperature protection. The range is 0°C to

156°C. If the setting value is out of range, the limit is 156 and the return value is 156.

[7:0]

Mantissa low bits

R/W

Mantissa low bits Y[7:0] value for linear format: X = Y × 2N.
