ON Semiconductor CAT810MTBI Voltage Supervisor IC

The ON Semiconductor CAT810MTBI is a precision voltage supervisor device designed to ensure the stability of electronic systems by monitoring the voltage levels and providing a reset signal whenever necessary. This microprocessor supervisory circuit is an essential component for applications that demand high reliability and accuracy in voltage monitoring.

Featuring a 4.38V threshold voltage, the CAT810MTBI is particularly well-suited for 5V systems, where it can accurately detect under-voltage conditions. Upon detection of a voltage drop below the threshold, the device generates a reset signal, which is maintained for a minimum of 140ms after the supply voltage rises above the reset threshold. This reset delay ensures that the system has sufficient time to stabilize before normal operation resumes.

The CAT810MTBI comes in a compact SOT-23 package, making it an ideal choice for space-constrained applications. Its low power consumption is an added advantage for portable and battery-powered devices, where power efficiency is critical. The device also features an active-low, push-pull reset output, which provides a direct interface to the reset pin of a microprocessor without the need for external components.

Key features of the CAT810MTBI include:

• Precision monitoring of 5V power supplies
• 4.38V threshold voltage for accurate under-voltage detection
• 140ms minimum reset pulse width to ensure system stability
• Low power consumption suitable for battery-operated devices
• Compact SOT-23 package for space-saving designs
• Active-low, push-pull reset output for easy integration

Overall, the CAT810MTBI from ON Semiconductor is a reliable and efficient solution for voltage supervision in a variety of electronic systems, including computers, controllers, and intelligent instruments. Its precision voltage monitoring and reset capabilities help to protect against data loss and ensure that systems operate within their specified voltage ranges, contributing to the longevity and dependability of the application it serves.
