SLUSCS3H – OCTOBER 2017 – REVISED JULY 2021

BQ298xyz Voltage, Current, Temperature Protectors with an Integrated High-Side

NFET Driver for Fast/Flash Charging Single-Cell Li-Ion and Li-Polymer Batteries

1 Features

3 Description

•

Voltage protection:

The BQ298xyz family of devices, featuring integrated

charge-pump FET drivers, provides high-side primary

battery cell protection for 1-series Li-ion and Li-

Polymer batteries, enabling consistent Rdson across

cell voltages. For better system thermal performance,

the BQ298x device's accuracy enables the use of a

sense resistor as low as 1 mΩ.

– Overvoltage (OV): ±10 mV

– Undervoltage (UV): ±20 mV

Current protection

– Overcurrent in charge (OCC): ±1 mV

– Overcurrent in discharge (OCD): ±1 mV

– Short circuit in discharge (SCD): ±5 mV

Temperature protection:

– Overtemperature (OT)

Additional features:

– Supports as low as a 1-mΩ sense resistor

•

The CTR pin in the BQ298x device can be configured

to override the FET driver by host control to create a

system reset or shutdown function. Alternatively, the

CTR pin can be configured to connect an external

Positive Temperature Coefficient (PTC) thermistor for

FET OT protection in addition to the internal die

temperature sensor. The BQ2980xy devices support

zero-volt (0-V) charging, while the BQ2982xy devices

have this disabled.

)

– High-side protection

– High Vgs FET drive

– 0-V charging (only BQ2980)

– CTR pin for FET override control for system

reset/shutdown

– Configure CTR for second OT protection

through an external PTC thermistor

Current consumption:

– NORMAL mode: 4 µA

– SHUTDOWN mode: 0.1-µA maximum
