GND: Ground Pin.
SW: Switch Output. The Schottky catch diode must be
placed with very short lead length in close proximity to SW
pin and GND.
V CC : Supply for the Chip. For good bypass, a low ESR
capacitor of 10 μ F or higher is required, with the lead length
kept to a minimum. V CC should be between 8V and 28V
and at least 2V higher than V BAT for V BAT less than 10V, and
2.5V higher than V BAT for V BAT greater than 10V. Under-
voltage lockout starts and switching stops when V CC goes
below 7V. Note that there is a parasitic diode inside from
SW pin to V CC pin. Do not force V CC below SW by more
than 0.7V with battery present. All V CC pins should be
shorted together close to the pins.
BOOST: This pin is used to bootstrap and drive the switch
power NPN transistor to a low on-voltage for low power
dissipation. In normal operation, V BOOST = V CC + V BAT
when switch is on. Maximum allowable V BOOST is 55V.
SENSE: Current Amplifier CA1 Input. Sensing can be at
either terminal of the battery. Note that current sense
resistor R S1 (0.08 ? ) is between Sense and BAT pins.

BAT: Current Amplifier CA1 Input.
PROG: This pin is for programming the charging current
and for system loop compensation. During normal opera-
tion, V PROG stays close to 2.465V. If it is shorted to GND
the switching will stop. When a microprocessor-controlled
DAC is used to program charging current, it must be
capable of sinking current at a compliance up to 2.465V.
V C : This is the control signal of the inner loop of the current
mode PWM. Switching starts at 0.7V and higher V C
corresponds to higher charging current in normal opera-
tion. A capacitor of at least 0.1 μ F to GND filters out noise
and controls the rate of soft start. To shut down switching,
pull this pin low. Typical output current is 30 μ A.
OVP: This is the input to the amplifier VA with a threshold
of 2.465V. Typical input current is about 50nA into pin. For
charging lithium-ion batteries, VA monitors the battery
voltage and reduces charging current when battery volt-
age reaches the preset value. If it is not used, the OVP pin
should be grounded.
