The PT7M7809STEX is a 1-channel voltage supervisor IC manufactured by Diodes Incorporated. It monitors a single voltage rail and asserts a reset signal when the monitored voltage falls below the fixed threshold of 2.93V. The device operates from a supply voltage up to 5.5V and provides a reset output with a minimum timeout period of 140ms, with a typical delay of 200ms.
This supervisor is housed in a compact SOT23-3 package, making it suitable for space-constrained applications. It is designed for use in systems requiring reliable power-on reset and voltage monitoring, such as microcontrollers, DSPs, and other digital logic circuits. The fixed threshold eliminates the need for external resistor dividers, simplifying design.
The PT7M7809STEX ensures proper system initialization by holding the reset output active for the specified timeout after the monitored voltage rises above the threshold. This prevents erratic operation during power-up and brown-out conditions.
