BQ32000DR TI Real Time Clock

The BQ32000DR from Texas Instruments is an industry-standard compatible real-time clock with an integrated trickle charger and automatic backup supply switching, enabling seamless transition to a capacitor or non-rechargeable battery during power loss. For selection, its I²C interface supports serial clock speeds up to 400kHz, while the programmable calibration adjustment from -63ppm to +126ppm and integrated oscillator-fail detection flag provide precise timekeeping and diagnostic visibility. The device operates from a 3V to 3.6V supply, drawing a timekeeping current of just 100µA maximum, making it suitable for low-power designs. In application, it excels on PC and laptop motherboards, single-board computers, and embedded systems requiring reliable timestamping and scheduling. It is also ideal for automotive electronics, telecom equipment, programmable logic controllers, and consumer devices such as smartphones, tablets, and wearables. Additional scenarios include smart meters, industrial meters, home automation, and IoT nodes where accurate, battery-backed timekeeping across a -40°C to +85°C range is critical.
