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.
Features
• Wide range battery current measurement; On-chip temperature
measurement
• Four battery voltage measurements with internal resistor dividers, and
up to five direct voltage measurements for use with an external resistor
divider
• Measurement synchronization between voltage channels and current
channels
• Five external temperature sensor inputs with internal supply for
external sensors
• Low-power modes with low-current operation
• Multiple wake-up sources: LIN, timer, high-voltage input, external CAN
interface, and current threshold and integration
• Precision internal oscillator and connections for external crystal
• LIN 2.2/ 2.1/ 2.0 protocol and physical interface
• msCAN protocol controller, and supply capability for 8 and 14 pin CAN
interfaces
• MM9Z1_638: S12Z microcontroller with 96/128 kByte Flash, 8.0 kByte
RAM, 4.0 kByte EEPROM
