Voltage Protection for 3 to 6 Series Cell Lithium-Ion/Polymer Batteries

Check for Samples: bq77PL157A4225

FEATURES

DESCRIPTION

•

Single IC Li-Ion Protection for 3 to 6 Series

Cells

The bq77PL157 is a stackable overvoltage protection

device for 3, 4, 5 or 6 series cell Li-Ion battery packs.

This device incorporates a precise and accurate

overvoltage detection circuit with preconfigured

threshold limits. Additional features include the ability

to stack multiple parts to monitor up to 18 series

cells. Preconfigured options include latched

(permanent) or recoverable fault output, as well as

specific voltage threshold limits selectable in 25 mV

steps.

•

Stackable to Protect up to 18 Series Cells

Programmable Detection Time Delay

Low Power Consumption

–

Typical 2 µA to 2.5 µA Normal Mode

•

Fixed Overvoltage Thresholds Available From

3.75 V to 4.35 V in 25-mV Steps

Highly Accurate: ±20 mV MAX, T_A= 0°C to

50°C

FUNCTION

Output Activation for Low Side FET

(Contact TI for Alternate Output Options:

High/Low-side Fuse or FET.)

Each series cell in a Li-Ion battery pack is compared

to an internal reference voltage. If one cell reaches

an overvoltage condition, the protection sequence

begins. The bq77PL157 starts charging an external

capacitor through the CD pin. When the CD pin

voltage reaches 1.2 V, the OUT pin changes state

and the LVO pin becomes active.

•

Protected Output, Power, and Ground Pins for

Added Safety and Reliability

•

Permanent or Recoverable Fault Options

16-pin Small Outline Package

If multiple bq77PL157 devices are stacked, the LVIN

pin of the next-lower device receives the LVO pin

APPLICATIONS

•

Primary or Secondary Level Voltage Protection

shortened delay timer before activating its OUT pin.

(No additional isolation or level-shift circuitry is

required.) The lowest bq77PL157 in the string is used

to activate a power MOSFET located in the low side

of the power path.
