The CAT853TTBI-T3 from ON Semiconductor is a supervisory circuit designed to monitor power supplies in digital systems. It generates a reset signal that is asserted when the power supply voltage falls below a preset threshold and remains low for at least 140 ms after the voltage rises above that level.
This device offers precision monitoring for +3.3V and 5.0V power supplies, with a specific threshold voltage of 3.08V. The reset output is active low and features an open drain or open collector configuration, requiring a pull-up resistor. It guarantees correct operation down to 1.0V VCC and provides power supply transient immunity.
The CAT853TTBI-T3 is housed in a compact SOT-23-3 package, suitable for surface mount applications. It operates within an industrial temperature range of -40°C to +85°C, making it suitable for various embedded control systems, computers, and handheld equipment.
Key features include a 140ms minimum reset timeout and immunity to power supply transients. This supervisor is designed for applications requiring reliable power monitoring and system reset.
