MM9Z1I638
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 ms CAN 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.
