LTC4065/LTC4065A
PI FU CTIO S
GND (Pin 1): Ground.
CHRG (Pin 2): Open-Drain Charge Status Output. The
charge status indicator pin has three states: pull-down,
pulse at 2Hz and high impedance state. This output can be
used as a logic interface or as an LED driver. When the
battery is being charged, the CHRG pin is pulled low by an
internal N-channel MOSFET. When the charge current
drops to 10% of the full-scale current, the CHRG pin is
forced to a high impedance state. If the battery voltage
remains below 2.9V for one quarter of the charge time, the
battery is considered defective and the CHRG pin pulses at
a frequency of 2Hz.
ACPR (Pin 5, LTC4065A Only): Open-Drain Power Supply
Status Output. When V CC is greater than the undervoltage
lockout threshold (3.6V) and V BAT + 80mV (if V BAT > 3.6V),
the ACPR pin will be pulled down to ground; otherwise the
pin is high impedance.
PROG (Pin 6): Charge Current Program and Charge Cur-
rent Monitor Pin. Connecting a 1% resistor, R PROG , to
ground programs the charge current. When charging in
constant-current mode, this pin servos to 1V. In all modes,
the voltage on this pin can be used to measure the charge
current using the following formula:
BAT (Pin 3): Charge Current Output. Provides charge
current to the battery and regulates the final float voltage
I BAT =
V PROG
R PROG
? 1000
to 4.2V. An internal precision resistor divider on this pin
sets the float voltage and is disconnected in shutdown mode.
V CC (Pin 4): Positive Input Supply Voltage. This pin
provides power to the charger. V CC can range from 3.75V
to 5.5V. This pin should be bypassed with at least a 1 μ F
capacitor. When V CC is within 32mV of the BAT pin
voltage, the LTC4065 enters shutdown mode, dropping
I BAT to about 1 μ A.
Floating the PROG pin sets the charge current to zero
(LTC4065) or puts the part in shutdown mode (LTC4065A).
In shutdown mode, the LTC4065A has less than 20 μ A
supply current and about 1 μ A battery drain current.
Exposed Pad (Pin 7): Ground. The Exposed Pad must be
soldered to the PCB ground to provide both electrical con-
tact and rated thermal performance.
EN (Pin 5, LTC4065 Only): Enable Input Pin. Pulling this
pin above the manual shutdown threshold (V MS is typi-
cally 0.82V) puts the LTC4065 in shutdown mode. In
shutdown mode, the LTC4065 has less than 20 μ A supply
current and less than 1 μ A battery drain current. Enable is
the default state, but the pin should be tied to GND if unused.
