When constant current mode is invoked, the internal
timer is reset.
The charge current is established using a single
resistor from PROG to V SS . The program resistor and
the charge current are calculated using the following

EQUATION 5-1:
If the internal timer expires before the recharge voltage
threshold is reached, a timer fault is indicated and the
charge cycle terminates. The MCP73113/4 device

When the voltage at the V BAT pin reaches the
regulation voltage, V REG , constant voltage regulation
begins. The regulation voltage is factory set to 4.10V,
4.20V, 4.35V or 4.40V with a tolerance of ±0.5%.

The charge cycle is terminated when, during constant
voltage mode, the average charge current diminishes

7.5%, 10% or 20% of fast charge current or internal
timer has expired. A 1 ms filter time on the termination
comparator ensures that transient load conditions do
not result in premature charge cycle termination. The
timer period is factory set and can be disabled. Refer to
period options.

The MCP73113/4 device continuously monitors the
voltage at the V BAT pin in the charge complete mode. If
the voltage drops below the recharge threshold,
another charge cycle begins and current is once again
supplied to the battery or load. The recharge threshold

For the MCP73113/4 devices with no recharge option,
the MCP73113/4 will go into standby mode when
termination condition is met. The charge will not restart
until the following conditions have been met:
? Battery is removed from the system and inserted
again
? V DD is removed and plugged in again
? R PROG is disconnected (or high impedance) and
reconnected
