The ADuC7033 is a complete system solution for battery monitoring in 12 V automotive applications. The device integrates 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 two integrated, 16-bit, Σ-Δ ADCs. The ADCs precisely measure battery current, voltage, and temper-ature to characterize the state of health and charge of the car battery.
A 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 ADuC7033 to the main electronic control unit (ECU) via a local interconnect network (LIN) interface that is integrated on-chip.
Both the MCU and the ADC subsystem can be individually configured to operate in normal or flexible power-saving modes of operation.
