Programmable Voltage, Programmable Current, Low Noise

RFPoL Step-Down Voltage Regulator

0x01: Interrupt #1

0x02: Interrupt #2

The registers 0x01 and 0x02 are Read Only. These 2 registers indicate cause(s) of the latest interrupt event by setting 1 at

corresponding bit(s), so bit(s) of 0 mean nothing happened (normal). In the Reg01 and Reg02, trigger events setting 1 are

described. See Interrupt Output.

Bits in these registers will be automatically cleared by reading the value with an I

2C command.

This automatic bit-clear action applies if the cause of an interrupt is resolved at the timing of a READ action.

For most of the bits in 0x01 and 0x02, the automatic bit-clear happens because these protection events

trigger shutdown actions to resolve the error situation.

(un-used bit)

Out of Range, SYNC Input

Becomes 1 when the SYNC pin input clock is out of range. See

Clock Synchronizer.

Out of Range, RFREQ

Becomes 1 when the RFREQ value, probed, is out of range. See

RFREQ Protection.

TSD(HARD) Event

Becomes 1 when the TJ exceeds the TSD(HARD) threshold. See

Thermal Protection.

TSD(SOFT) Event

Becomes 1 when the TJ exceeds the TSD(SOFT) threshold. See

Thermal Protection.

(un-used bit)

VIT(OVLO) Event

Main-buck Over-current Event

Becomes 1 when the output current in Over-Current Protection.

VOVP Event

Becomes 1 when the VO exceeds the VOVP threshold. See Over-

Voltage Protection

VUVP(CV) or VUVP(CC) Event

Becomes 1 when the VO falls below the VUVP(CV) or VUVP(CC)

threshold. See Under-Voltage Protection.

AUX LDO Under-voltage

See AUX LDO Under-Voltage Protection

IOCP(V5V) Event

Becomes 1 when the output current of the mini-buck exceeds the

IOCP(V5V) threshold. See Mini-buck Over-Current Protection.

VOVP(V5V) Event

Becomes 1 when the VO(V5V) exceeds the VOVP(V5V) threshold. See

Mini-buck Over-Voltage Protection.

VUVP(V5V) Event

Becomes 1 when the VO(V5V) falls below the VUVP(V5V) threshold. See

Mini-buck Under-Voltage Protection.

0x03: Status Flag

The register 0x03 is Read Only type. It indicates various status flags from internal circuit blocks.
