BQ32002DR Description

Short technical summary and product information.

The BQ32002DR from Texas Instruments is a real-time clock (RTC) with integrated calendar and I²C interface. It includes automatic switchover to a backup supply (capacitor or non-rechargeable battery) and a trickle charger. Key features include leap-year compensation, square wave output, and programmable calibration adjustment from -63 ppm to +126 ppm. The device also features integrated oscillator-fail detection with a flag register.

 

The RTC operates from a supply voltage range of 1.4V to 3.6V, with a typical timekeeping current of 65 µA at 3.3V. It supports I²C serial communication up to 400 kHz and requires an external 32.768 kHz crystal. The operating temperature range is -40°C to +85°C.

 

The BQ32002DR is housed in an 8-pin SOIC package (8-SOIC, 3.90mm width) and is surface-mountable. It is designed for applications requiring accurate timekeeping with backup power, such as industrial controls, consumer electronics, and battery-powered systems.
