HZ_MODE Bit (High Impedance Mode Enable)
The HZ_MODE bit in the control register (0x02h) is used to disable or enable the high impedance
mode. A low logic level (0) on this bit enables the IC and a high logic level (1) puts the IC in a low
quiescent current state called high impedance mode. When in high impedance mode, the converter is
off and the battery FET and BGATE are on. The load on SYS is supplied by the battery.
Control/Battery Voltage Register (READ/WRITE)
Memory location: 03, Reset state: 0001 0100
BIT NAME Read/Write FUNCTION
B7 (MSB) V
BREG5
Read/Write Battery Regulation Voltage: 640 mV (default 0)
B6 V
BREG4
Read/Write Battery Regulation Voltage: 320 mV (default 0)
B5 V
BREG3
Read/Write Battery Regulation Voltage: 160 mV (default 0)

B1 I
INLIMIT
Read/Write Input Limit for IN input-
0 – 1.5A
1 – 2.5A (default 0)
B0 (LSB) D+/D–_EN Read/Write 0 – Normal state, D+/D- Detection done
1 – Force D+/D– Detection. Returns to “0” after detection is done. (default 0)
• Charge voltage range is 3.5V–4.44V with the offset of 3.5V and step of 20mV (default 3.6V).
• Before writing to increase VBATREG register following a BATOVP event (e.g., IN or USB voltage is applied,
IC remains in DEFAULT mode and then VBAT>3.6V is attached), toggle the HiZ bit or CD pin to clear the
BATOVP fault.
