ADuC7036 is a precision battery sensor for automotive applications. It integrates high precision ADCs, microcontroller and multiple battery interfaces, and can measure battery voltage, current, temperature, etc. It is widely used in automotive power management, BMS and electric vehicle charging pile.
The ADuC7036 is an integrated precision battery sensor for automotive applications, featuring dual 16‑bit ADCs, a programmable voltage reference, and an ARM7TDMI core with up to 20.48 MHz PLL. The device operates from a 12 V battery supply and includes on‑chip flash, SRAM, LIN, SPI, UART, and watchdog peripherals.
The handbook includes electrical and timing specifications, absolute maximum ratings, pin configuration, typical performance characteristics, and an ordering guide for the 48‑lead LFCSP package. It also details the ADC operation modes, power‑supply monitoring, and LIN/BSD communication interfaces.
