The BU4221G-TR from ROHM Semiconductor is a single-channel voltage detector IC designed for simple reset and power-on reset applications. It operates at 2.1V and features an active low reset output, which can be configured as open drain or open collector. The reset timeout is adjustable or selectable, providing flexibility in system design.
This supervisor IC is suitable for monitoring a single voltage level and is housed in a compact 5-SSOP package (SC-74A, SOT-753) designed for surface mounting. The operating temperature range is from -40°C to 125°C, making it suitable for a wide variety of environmental conditions. Its primary function is to ensure system stability by providing a reset signal during power-up or voltage fluctuations.
The BU4221G-TR is RoHS3 compliant and has an MSL 1 rating, indicating its suitability for standard electronic manufacturing processes. Its simple reset functionality and reliable performance make it a valuable component in embedded systems requiring stable power management.
