PIU
the voltage on this pin can be used to measure the charge
current using the following formula:
I
BAT
= (V
PROG

PROG
) 1000
This pin is clamped to approximately 2.4V. Driving this pin
to voltages beyond the clamp voltage can draw currents as
high as 1.5mA.
V
CC
(Pin 6):
Positive Input Supply Voltage. Provides
power to the charger. V
CC
can range from 4.25V to 6.5V.
This pin should be bypassed with at least a 1
μ
F capacitor.
When V
CC
is within 100mV of the BSENSE pin voltage, the
LTC4058 enters shutdown mode dropping the battery
drain current to less than 2
μ
A.
ACPR (Pin 7):
Power Supply Status Open-Drain Output.
When V
CC
is greater than the undervoltage lockout thresh-
old and at least 100mV above V
BSENSE
, 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 LTC4058 into shutdown mode where the battery drain
current is reduced to less than 2
μ
A and the supply current
is reduced to less than 50
μ
A. A logic low or floating the EN
pin (allowing an internal 2M
pull-down resistor to pull
this pin low) enables charging.
