ADuC7036: Integrated Precision Battery Sensor for Automotive
The ADuC7036 is a complete system solution for battery monitoring in 12 V automotive applications. These devices integrate all of the required features to precisely and intelligently monitor, process, and diagnose 12 V battery parameters including battery current, voltage, and temperature over a wide range of operating conditions.
Minimizing external system components, the device is powered directly from the 12 V battery. An on-chip, low dropout regulator generates the supply voltage for three integrated, 16-bit, Σ-Δ ADCs. The ADCs precisely measure battery current, voltage, and temperature to characterize the state of health and charge of the car battery.
TA Flash/EE memory-based ARM7™ microcontroller (MCU) is also integrated on-chip. It is used to both preprocess the acquired battery variables and to manage communications from the ADuC7036 to the main electronic control unit (ECU) via a local interconnect network (LIN) interface that is integrated onchip.Both the MCU and the ADC subsystem can be individually configured to operate in normal or flexible power saving modes of operation.
