OPERATION
Introduction
The LTC4095 is a linear battery charger designed to
charge single-cell lithium-ion batteries. The charger uses
a constant-current/constant-voltage charge algorithm
with a charge current programmable up to 950mA. Ad-
ditional features include automatic recharge, an internal
termination timer, low-battery trickle charge conditioning,
bad-battery detection, and a thermistor sensor input for
out of temperature charge pausing.
Futhermore, the LTC4095 is capable of operating from a
USB power source. In this application, charge current can
be programmed to a maximum of 100mA or 500mA per
USB power specications.
Input Current vs Charge Current
The LTC4095 regulates the total current delivered to the
BAT pin; this is the charge current. To calculate the total
input current (i.e., the total current drawn from the IN pin),
it is necessary to sum the battery charge current, charger
quiescent current and PROG pin current.
Undervoltage Lockout (UVLO)
The undervoltage lockout circuit monitors the input volt-
age (IN) and disables the battery charger until IN rises
above VUVLO (typically 4V). 200mV of hysteresis prevents
oscillations around the trip point. In addition, a differential
undervoltage lockout circuit disables the battery charger
when IN falls to within VDUVLO (typically 40mV) of the
BAT voltage.
Suspend Mode
The LTC4095 can also be disabled by pulling the SUSP
pin above 1.2V. In suspend mode, the battery drain cur-
rent is reduced to 1.3A and the input current is reduced
to 8.5A.
