The CAT809RTBI-T3 from On Semiconductor is a 3-pin microprocessor power supply supervisor designed to monitor power supplies in digital systems. It generates a reset signal that is asserted when the power supply voltage drops below a preset threshold and remains asserted for at least 140 ms after the supply has risen above the threshold.
This device features a precise monitoring capability for power supplies, with a specific threshold voltage of 2.63V. The reset output is active low and configured in a push-pull, totem pole configuration. It operates reliably down to 1.0V VCC and consumes a low supply current of 6µA.
The CAT809RTBI-T3 is suitable for applications operating within an industrial temperature range of -40°C to +85°C. It is supplied in a compact 3-pin SOT-23-3 surface mount package, making it ideal for space-constrained designs.
These supervisors are direct replacements for MAX803, MAX809, and MAX810 devices, offering robust power supply transient immunity. They are commonly used in computers, servers, laptops, wireless communications, embedded control systems, and intelligent instruments.
