FUNCTIONAL PIN DESCRIPTION
Description
Charging Output - This pin is wired to the positive terminal of the battery. (The negative battery terminal is wired to GND.)
Charge Current Programming Pin - A resistor (RCP) is connected between this pin and GND. The constant current is
determined
by
the
following
relationship:
IBAT(MAX)
=
65000
RCP
Compensation Pin – Connect a 0.1uF compensation capacitor from this pin to VDD.
Charge Termination Programming Pin – A resistor (RTP) is connected between this pin and GND. The termination charge
current
is
determined
by
the
following
relationship:
IBAT(MIN)
=
7500
RTP
Maximum VIN Current Programming Pin – A resistor (RUS) is connected between this pin and GND. The Hi Level charge
current
is
determined
by
the
following
relationship:
I
IN(HI))
=
1211
RUS
Common Ground
Not Connected. This pin is connected internally and should be left floating.
PMOS Switch driver – This output is designed to drive the gate of an external PMOS power switch. The driver is pulled low
(PMOS on state) when VDD > VBAT.
Common Power Node – Connects to system power bus.
State Select Input – Applying a two bit TTL compatible signal sets the desired state of the charger corresponding to the Truth
Table.
Voltage Input – Current limited USB input. Apply a USB compliant power input.
Voltage Mode Select - Selects the constant voltage. VM = Low to select 4.2V charge level. VM = High to select 4.1V charge
level.
Status - This pin is a logic high level when the battery is being charged. A low signal indicates either under voltage lockout,
charge completed, or VBAT > VDD, or VID0 = VID1 = 0.
