MAX809SQ463T1G Description

Short technical summary and product information.

The MAX809SQ463T1G 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 features a precision VCC monitor with a nominal threshold voltage of 4.63V and an active-low reset output. The reset signal is guaranteed to be asserted when VCC falls below 1.0V and is maintained for a factory-trimmed timeout period after VCC rises above the reset threshold, with a minimum power-on reset pulse width of 140ms.

 

This device operates over a wide temperature range of -40°C to 105°C, making it suitable for various applications including computers, embedded systems, and battery-powered equipment. It is optimized to reject fast transient glitches on the VCC line and requires no external components. The MAX809SQ463T1G is available in a compact SC-70-3 (SOT-323) surface-mount package, facilitating integration into space-constrained designs.

 

Key electrical characteristics include a supply voltage range of 1.2V to 5.5V and a low typical supply current of 0.5 µA at 3.2V. The output type is Push-Pull, Totem Pole. These features make it a reliable choice for critical microprocessor power supply monitoring.
