Intelligent battery sensor with CAN and LIN
MM9Z1_638
The MM9Z1_638 is a fully integrated intelligent battery monitoring system. The device supports precise current measurement via an external shunt resistor. It features four
voltage measurements via internal calibrated resistor dividers or external dividers. It includes an internal temperature sensor, allowing close proximity battery temperature measurements, plus four external temperature sensor inputs.
The MM9Z1_638 features the LIN 2.2 protocol and physical interface, as well as an msCAN protocol controller, for interfacing to automotive buses. The MM9Z1_638 is able to supply and control external CAN interfaces.
This device is powered by SMARTMOS technology.
