The MC33347A is a monolithic lithium battery protection circuit that is designed to enhance the useful operating life of one or two cell rechargeable battery packs. Cell protection features consist of independently programmable charge and discharge limits for both voltage and current, a delayed current shutdown, continuous cell voltage balancing with the choice of on–chip or external balancing resistors, and a virtually zero current sleepmode state when the cells are discharged.

Additional features include an on–chip charge pump for reduced MOSFET losses while charging or discharging a low cell voltage battery pack. This protection circuit requires a minimum number of external components and is targeted for inclusion within the battery pack. This MC33347A is available in standard and low profile 16 lead surface mount packages.

This is the drain connection to an internal MOSFET. An external resistor is placed from this pin

ББББББББББББББББББББББ

to the positive terminal of Cell 1 for increased cell balancing capability. This allows most of the additional power to be dissipated off–chip.

ББББББББББББББББББББББ

This is the drain connection to an internal MOSFET. An external resistor is placed from this pin to the positive terminal of Cell 2 for increased cell balancing capability. This allows most of the

ББББББББББББББББББББББ

additional power to be dissipated off–chip. This is a multifunction pin that connects to a high impedance node of the Cell Selector where it

is used to monitor the positive terminal of Cell 1 and the negative terminal of Cell 2. This pin

ББББББББББББББББББББББ

also provides logic biasing and a discharge path for the internal balancing of Cell 1. This is a multifunction pin that connects to a high impedance node of the Cell Selector where it

ББББББББББББББББББББББ

is used to monitor the positive terminal of Cell 2 and to provide positive supply voltage for the protection IC. This pin is also used to monitor the voltage drop across the discharge current

ББББББББББББББББББББББ

limit resistor to detect a discharge current or a high current threshold to trigger fast sampling. It also provides a discharge path for the internal balancing of Cell 2.

ББББББББББББББББББББББ

The bottom side of a three resistor divider string connects to this pin. The Cell Selector internally switches this point to the negative terminal of the cell that is to be monitored.

ББББББББББББББББББББББ

The top side of a three resistor divider string connects to this pin. The Cell Selector internally

ББББББББББББББББББББББ

switches this point to the positive terminal of the cell that is to be monitored. The upper tap of a three resistor divider string connects to this pin. The Cell Voltage Detector

compares the divided down cell voltage to an internal reference. If the comparator detects that

ББББББББББББББББББББББ

the cell voltage has fallen below the programmed level for three consecutive samples,

ББББББББББББББББББББББ

discharge switch Q2 is disabled, and the protection circuit enters into a low current sleepmode state. This prevents further discharging of the battery pack.

ББББББББББББББББББББББ

The lower tap of a three resistor divider string connects to this pin. The Cell Voltage Detector compares the divided down cell voltage to an internal reference. If the comparator detects that

ББББББББББББББББББББББ

the cell voltage has risen above the programmed level, charge switch Q1 is disabled, preventing further charging of the battery pack. A 2.0 µA current source pull–up is internally

ББББББББББББББББББББББ

applied to this pin creating input hysteresis. This pin is a common point that is used to monitor the voltage drop across the charge and

ББББББББББББББББББББББ

discharge current limit resistors. This pin is used to monitor the voltage drop across the charge current limit resistor or if

connected to Pin 16, prevents cell balancing from occuring.

ББББББББББББББББББББББ

This pin provides a gate turn–off path for charge switch Q1. The charge switch source and the

ББББББББББББББББББББББ

battery pack negative terminal connect to this point. This output connects to the gate of charge switch Q1 allowing it to enable or disable battery

pack charging.

ББББББББББББББББББББББ

This is a multifunction input that is used to program the number of cells and to facilitate circuit testing. This input is connected to Pin 3 for two cell operation, and to Pin 16 for one cell

ББББББББББББББББББББББ

operation. This output connects to the gate of discharge switch Q2 allowing it to enable or disable battery

pack discharging.

ББББББББББББББББББББББ

This is the charge pump output. A reservoir capacitor is connected from this pin to ground.

This is the protection IC ground and all voltage ratings are with respect to this pin.
