BQ29700DSER Description

Short technical summary and product information.

The BQ29700DSER from Texas Instruments is an advanced single-cell battery protector IC specifically designed for Lithium-ion (Li-ion) and Lithium-polymer (Li-Po) battery applications. This device provides crucial protection functions including overcharge detection (OVP), over-discharge detection (UVP), charge overcurrent detection (OCC), discharge overcurrent detection (OCD), and load short-circuit detection (SCP).

 

Key electrical specifications include a typical operating current of 4 µA and a maximum input voltage of 8 V. The overvoltage protection thresholds are configurable, with minimum protection at 3.85 V and maximum at 4.6 V. It also features a shutdown current of 100 nA, contributing to low power consumption.

 

The BQ29700DSER is housed in a compact 6-WSON (1.5x1.5 mm) surface-mount package, making it suitable for space-constrained designs. It operates within a wide temperature range of -40°C to 85°C (TA). The device includes FET drive outputs for both charge and discharge FETs and offers precise voltage sensing across external FETs for accurate overcurrent protection.

 

This battery protector is ideal for applications requiring reliable and robust battery safety, such as portable electronics, power tools, and energy storage systems. Its factory-programmed fault protection thresholds and fault recovery timers ensure consistent performance.
