Describe
Battery management 3 to 5 cell battery monitor IC 32-QFN

Product Description

The RAA4892553GNP battery front-end is a low-cost 3 to 5 cell battery monitor that can measure voltage/temperature and transmit it to the MCU for battery management. This device includes a current monitor and a 5-pin LED driver directly from the battery voltage, enabling low-cost display of charging status. The heat-resistant plug-in RAA4892553GNP also features a 100mV current wake-up detection and battery/wire open circuit detection function.


Characteristics

It is designed to be used in conjunction with the MCU as the front end of the battery for BMS with higher safety

Optimize integration to achieve very low costs

Voltage, temperature measurement, current detection, open circuit detection and direct drive from Vbat built-in LED

The selection of design and packaging engineering emphasizes cost optimization

Sample solution code can shorten the design time

Renesas is developing a set of Arm® -based solution codes that can serve as a complete ready-to-use solution or as a starting point for code development, thereby saving battery pack design time.

The code will be compatible with RA and FSP

Simple operation

Try to use as few complex internal state machines as possible to make the parts easier to understand

Provide important information for the battery pack MCU, but allow the battery pack design team to choose how to use this information

A wide battery voltage range of 4V to 30V, suitable for lithium-ion batteries with 3 to 5 cells

OCV status coding, used for LED SOC reporting

There are no internal OV, UV, OT or UT

100mV current wake-up detection

Battery/Wire Open Circuit Detection (OW

Two thermistor inputs support ±2.5°C temperature protection

Six high-voltage universal outputs (HVGPO) for leds, fuses, FETs, etc

Heat-resistant insertion and extraction

I2C interface with CRC

Low-cost BFE series

Battery monitoring function

32-pin QFN package, size 4mm x 4mm, pitch 0.4mm


Target application

Electric tools (hand drills, gardening tools)

Cleaning tools (portable vacuum cleaners, robot cleaners)

Telecommunications (ESS
