Introduction

AI Translation

The BQ2970 battery protection device provides an accurate monitoring and triggering threshold for overcurrent protection under high discharge/charge current operation or battery overcharge conditions. Package: – 6-pin DSE (1.50mm×1.50mm×0.75mm)

The BQ2970 device provides protection functions for lithium-ion/lithium-polymer batteries and monitors external power FETs to provide protection during high charge or discharge currents. In addition, there is also monitoring and protection for overcharged and depleted batteries. These features are achieved with extremely low current consumption during normal mode operation.

Features

  • Input voltage range: VSS – 0.3V to 12V
  • FET drive: CHG and DSG FET drive outputs
  • Voltage sensing on external FETs for OCP within ±5mV (typical)
  • Fault detection: OVP, UVP, OCC, OCD, SCP
  • Zero-voltage charging for depleted batteries
  • Factory-preset protection thresholds: fault detection voltage thresholds, fault trigger timers, fault recovery timers
  • Operating modes without battery charger enabled: normal mode I_CC = 4μA, shutdown I_CC = 100nA
  • Operating temperature range T_A = -40℃ to +85℃
