BD5245G-1TR

The ROHM Semiconductor BD5245G-1TR is a highly accurate, ultra-low current consumption CMOS voltage detector IC from the BD52xxG-1 series. This device is designed for applications requiring precise voltage monitoring and reset functionality. It features an Nch open-drain output and allows for delay time setting via an external capacitor.

Key specifications include a typical detection voltage of 4.5V with an accuracy of ±0.9% for voltages between 1.7V and 5.0V. The ultra-low current consumption is typically 270 nA, making it suitable for power-sensitive applications. The time delay accuracy is ±30% over the operating temperature range of -40°C to +85°C, provided the external capacitor on the CT pin is 1 nF or greater.

The BD5245G-1TR comes in a compact SSOP5 package, measuring 2.90 mm x 2.80 mm x 1.25 mm, which is similar to the SOT-23-5 package. This small footprint makes it ideal for space-constrained designs. The N.C. pin is electrically open and can be connected to VDD or GND.

This voltage detector is suitable for all consumer devices that require voltage detection, ensuring reliable operation by monitoring power supply levels and generating reset signals when necessary.
