The DS2438Z+ is a battery monitor integrated circuit with supervisor functions manufactured by Analog Devices. It offers high accuracy and low-cost monitoring of single cell lithium-ion, lead acid, NiMH, or alkaline batteries for multiple battery application systems. It is housed in a small SO8 package and operates over a voltage range of 2.4 to 10VDC. The IC has integrated several features such as high-accuracy voltage and current measurement, integrated thermistor and humidity measurement functionality, provides a wide range of configurable alerts, and has an integrated analog-to-digital converter with an 8-bit resolution providing accurate readings. It also provides status monitoring such as the voltage of the battery, current, temperature and state of battery charge/discharge. Additionally, an embedded EEPROM can be used to store calibration information and measurements, allowing the IC to be reused in multiple systems.
