Diodes, a supplier of application specific standard products within the discrete, logic, analog and mixed-signal semiconductor markets, has introduced the APX803L micro-power voltage detector. It is designed to support the supervisory circuits of microprocessors and microcontrollers by enabling accurate monitoring of voltage levels and will generate a reset signal whenever a supply rail falls below a defined threshold, according to the company. This function is required by many systems such as computers, communications equipment, and portable battery-powered devices.

Offered in a detection voltage level range of 1.2V to 5.0V in 0.1V steps, the APX803L provides a threshold accuracy of +/-1.5%, while consuming just 1 microamps and requiring no external components, according to Diodes. Whenever the monitored VCC power supply rail drops below the chosen threshold, the APX803L asserts a reset signal within 20 microseconds that is held until the supply rail recovers to a level above the threshold. The device's reset pin provides an open-drain, active-low output with device ordering options that allow for delay times of 0ms, 55ms, 220ms, or 450ms.

The APX803L is available in 3-pin SOT23, SOT323, and SC59 packages, as well as a 5-pin SOT25 package, and supports drop-in replacements and original designs.
