onsemi Integrated Circuits (ICs) - PMIC - Supervisors CAT859CTBI-GT3

The CAT859CTBI-GT3 is a microprocessor power supply supervisor designed to monitor power supplies in digital systems. It generates an active low reset signal when the power supply voltage falls below a preset threshold and maintains this signal for at least 140 ms after the voltage rises above the threshold. This device supports standard threshold levels for +3.3 V and 5.0 V systems, making it versatile for various applications. Key features include precision monitoring with a reset threshold voltage tolerance of -5% to -10%, a low supply current of 6 ¬µA, and operation down to a VCC of 1.0 V. The CAT859CTBI-GT3 is housed in a compact SOT-23 package and operates over an industrial temperature range of -40¬8C to +85¬8C. It is suitable for use in computers, servers, laptops, wireless communications, and embedded control systems. The device is also Pb-free and RoHS compliant, ensuring it meets environmental standards.
