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
