Description

[7:4]

OCP_BLANK[3:0]

Configures fixed time-blanking interval tOCP for overcurrent protection

(OCP). The value is an unsigned integer in the range of 0

value15.

[3:1]

OLP_BLANK[2:0]

Configures fixed time blanking interval tOLP for open loop protection (OLP)

and sense resistor protection. The value is an unsigned integer in the range

of 0

value7.

[0]

IOTP_SAMP

Sample internal temperature sensor at a slower rate when not in internal

overtemperature state (iOTP fault state). Recommended to set bit

IOTP_SAMP to sample slow.

0 = Sample fast

1 = Sample slow

OCP_CNT[2:0]

Sets the second stage OCP fault counter threshold used when declaring a

fault.

0 = Force OCP fault (debug only)

1-7= Number of times an OCP fault has to occur consecutively.

[4]

OCP_LAT

Configures OCP fault type.

0 = Unlatched fault

1 = Latched fault

[3:1]

OLP_CNT[2:0]

Sets the second stage OLP fault counter threshold used when declaring a

fault.

0 = Force OLP fault (debug only)

1-7= Number of times an OLP fault has to occur consecutively before the

IC will enter a fault state.

[0]

OLP_LAT

Configures OLP fault type.

0 = Unlatched fault

1 = Latched fault
