BIT(S)

SYMBOL

OPERATION

b[15]

Mfr_pg_fault_sel_vout_ov

1: Output overvoltage mapped to PG pin with additional deglitching equal to Mfr_pg_ov_uv_deglitch.

Only applies if Mfr_pg_operation=10b or 11b.

0: Output overvoltage not mapped to PG pin.

b[14]

Mfr_pg_fault_sel_vout_uv

1: Output undervoltage mapped to PG pin with additional deglitching equal to Mfr_pg_ov_uv_deglitch.

Only applies if Mfr_pg_operation=10b or 11b.

0: Output overvoltage not mapped to PG pin.

b[13]

Mfr_pg_fault_sel_iout_oc

Not supported

b[12]

Mfr_pg_fault_sel_iout_uc

Not supported

b[11]

Mfr_pg_fault_sel_temp_ot

1: Overtemperature mapped to PG pin. Only applies if Mfr_pg_operation=10b or 11b.

0: Overtemperature not mapped to PG pin.

b[10]

Mfr_pg_fault_sel_temp_ut

1: Undertemperature mapped to PG pin. Only applies if Mfr_pg_operation=10b or 11b.

0: Undertemperature not mapped to PG pin.

b[9]

Mfr_pg_fault_sel_vin_ov

1: Input overvoltage mapped to PG pin. Only applies if Mfr_pg_operation=10b or 11b.

0: Input overvoltage not mapped to PG pin.

b[8]

Mfr_pg_fault_sel_vin_uv

1: Input undervoltage mapped to PG pin. Only applies if Mfr_pg_operation=10b or 11b.

0: Input undervoltage not mapped to PG pin.

b[7]

Mfr_pg_fault_sel_ton_max

1: TON_MAX_FAULT sequencing fault mapped to PG pin. Only applies if Mfr_pg_operation=10b or 11b.

0: TON_MAX_FAULT sequencing fault not mapped to PG pin.

b[6]

Mfr_pg_fault_sel_vout_en

1: Inverted output enable mapped to PG pin.

0: Inverted output enable not mapped to PG pin.

b[5]

Reserved

Reserved, always returns 0

b[4:2]

Mfr_pg_ov_uv_deglitch

Additional deglitch value for assertion and de-assertion of overvoltage and undervoltage signals to PG:

111b: 100ms

110b: 50ms

101b: 20ms

100b: 10ms

011b: 5ms

010b: 1ms

001b:200μs

000b: There is no additional deglitch delay applied to the signal

b[1:0]

Mfr_pg_operation

11b: Active Hi-Z propagation of faults according to Mfr_pg_fault_sel

10b: Active low propagation of faults according to Mfr_pg_fault_sel

01b: Reserved

00b: Force PG pin to value set by Mfr_pg_gpo_force in MFR_PG_GPO register
