ON Semiconductor CAT810MTBI-GT3 Voltage Supervisor IC

The CAT810MTBI-GT3 from ON Semiconductor is a precision voltage supervisor device designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. This microprocessor (µP) supervisory circuit is a vital component for systems that require a high level of reliability and accuracy in voltage monitoring.

With a threshold voltage of 4.38V and an active low reset output, the CAT810MTBI-GT3 is ideal for managing 5V power supplies. The reset signal it generates is guaranteed to remain asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring that the system has sufficient time to stabilize before the processor begins operation. This feature is crucial for preventing system errors that can occur if the processor attempts to start up with an unstable power supply.

The device is available in a small 3-pin SOT-23 package, making it suitable for use in space-constrained applications. Its low power consumption and wide operating temperature range of -40°C to 85°C make it an excellent choice for portable electronics, as well as industrial and automotive applications where robust performance is required under varying environmental conditions.

Key features of the CAT810MTBI-GT3 include:

• Precision monitoring of 5V power supplies
