The BD47xx series is a reset IC that was developed to prevent system errors at transient state when the power of CPU or logic circuit switches ON/OFF or momentary shut down.
The BD47xx series from ROHM is a reset IC designed to prevent system errors during power‑on/off transients. It provides a single reset output and operates with ultra‑low current consumption, making it suitable for portable electronic devices.
The device is offered in a compact SSOP5 package (2.90 mm × 2.80 mm × 1.15 mm) and includes specifications such as a detection voltage range of 1.9‑4.6 V, typical current consumption of 1.6 µA, and an operating temperature range of –40 °C to +75 °C.
