PM6613N

The PM6613N registers

•

Bit 2 AOV: ACDIV overvoltage

–

set by hardware when the PM6613N detects an ACDIV pin voltage higher than

2.625 V

–

0: no ACDIV overvoltage detected

–

1: ACDIV overvoltage detected

•

Bit 1 AUV: ACDIV undervoltage

–

set by hardware when the PM6613N detects an ACDIV pin voltage lower than 2 V

–

0: no ACDIV undervoltage detected

–

1: ACDIV undervoltage detected

•

Bit 0 HS: high-side short

–

set by hardware when a short condition is detected between drain and source of

the high-side MOS

–

0: no short detected on high-side MOS

–

1: short detected on high-side MOS

5.3

Charge current register (CHRG_AMP)

Address: 0x14

Reset value: 0x0000

•

Bits 13:6 AMP[13:6]: charge current configuration bits

–

these bits are written by software and fix the amount of current to be delivered

when battery is charging. Values are in mA. The range goes from 64 mA when

AMP[13:6] = 0x0040 to 16320 mA when AMP[13:6] = 0x3FC0. Minimum step is 64

mA.
