PIN DESCRIPTION
The descriptions of the pins are listed in Table 3-1.
TABLE 3-1:
PIN FUNCTION TABLES
3.1
Battery Management Input Supply
(V
DD
)
A supply voltage of [V
REG
(typ.) + 0.3V] to 6V is
recommended. Bypass to V
SS
with a minimum of
4.7
μ
F.
3.2
Battery Charge Control Output
(V
BAT
)
Connect to positive terminal of battery. Drain terminal
of internal P-channel MOSFET pass transistor. Bypass
to V
SS
with a minimum of 4.7
μ
F to ensure loop
stability when the battery is disconnected.
3.3
Charge Status Output (STAT)
STAT is an output for connection to an LED for charge
status indication. Alternatively, a pull-up resistor can
be applied for interfacing to a host microcontroller.
STAT is a tri-state logic output on the MCP73831 and
an open-drain output on the MCP73832.
3.4
Battery Management 0V Reference
(V
SS
)
Connect to negative terminal of battery and input
supply.
3.5
Current Regulation Set (PROG)
Preconditioning, fast charge and termination currents
are scaled by placing a resistor from PROG to V
SS
.
The charge management controller can be disabled by
allowing the PROG input to float.
Pin No.
