MAX809JTRG Description

Short technical summary and product information.

The MAX809JTRG from On Semiconductor is a cost-effective system supervisor circuit designed to monitor VCC in digital systems and provide a reset signal to the host processor when necessary. It requires no external components. The reset output is driven active within 10μs of VCC falling through the reset voltage threshold and is maintained active for a factory-trimmed timeout period after VCC rises above the threshold. This device features an active-low RESET output and is available in a SOT-23-3 package.

 

Key electrical characteristics include a nominal supply voltage of 4V, an active-low reset output, and a minimum reset timeout of 140ms. The device is optimized to reject fast transient glitches on the VCC line and has a low supply current of 0.5μA at 3.2V, making it suitable for battery-powered applications. The reset output is guaranteed to VCC = 1.0V.

 

This supervisor is ideal for critical microprocessor power supply monitoring in computers and embedded systems. Its compact SOT-23-3 (TO-236) surface-mount package makes it suitable for space-constrained designs. The operating temperature range is -40°C to 105°C (TJ).
