LTC4068-4.2/LTC4068X-4.2
406842fa
When VCC is within 100mV of the BAT pin voltage, the
LTC4068 enters shutdown mode dropping the battery
drain current to less than 2µA.
ACPR (Pin 7): Power Supply Status Open-Drain Output.
When VCC is greater than the undervoltage lockout thresh-
old and at least 100mV above VBAT, the ACPR pin is pulled
to ground; otherwise, the pin is high impedance.
EN (Pin 8): Enable Input . A logic high on the EN pin will put
the LTC4068 into shutdown mode where the battery drain
current is reduced to less than 2µA and the supply current
is reduced to less than 50µA. A logic low or floating the EN
pin (allowing an internal 2MΩ pull-down resistor to pull
this pin low) enables charging.
PI FU CTIO S
PROG (Pin 5): Charge Current Program and Charge Cur-
rent Monitor. Charge current is programmed by connect-
ing a 1% resistor, RPROG, to ground. 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:
IBAT = (VPROG/RPROG) • 1000
This pin is clamped to approximately 2.4V. Driving this pin
to voltages beyond the clamp voltage can draw large
currents and should be avoided.
VCC (Pin 6): Positive Input Supply Voltage. Provides
power to the charger. VCC can range from 4.25V to 6.5V.
This pin should be bypassed with at least a 1µF capacitor.
