RD9Z1-638-12V-C

RD9Z1-638-12V-C is a reference design for 12V lead-acid battery applications and features the MM9Z1J638 battery sensor module. The RD9Z1-638-12V-C is built to demonstrate the product capabilities in a 12V lead-acid application where high EMC performance is required to obtain high accuracy measurements on key battery parameters. The key measurement parameters are battery voltage, current and temperature. The embedded microcontroller obtains those parameters and calculates the battery State-of-Charge (SOC), State-of-Health (SOH) and State-of-Function (SOF).

• 12V lead-acid battery sensor with CAN
