DiodesZetex Voltage Supervisor 1 Supervisor 3-Pin Surface Mount SOT-23 Package 2.63 V Reset Threshold APX803-26SAG-7

DiodesZetex APX803-26SAG-7 voltage supervisor is a compact microprocessor supply voltage monitor designed for use in a variety of electronic systems including desktop computers, laptops, notebooks, test instruments, and portable battery-powered devices. Housed in a small 3-pin SOT-23 package, it provides reliable monitoring and supervisory capabilities at a reset threshold voltage of 2.63 V.

This device acts as a microprocessor reset monitor by supervising a single voltage rail, ensuring that system reset is triggered only when voltage falls below the specified threshold. It features an active low output driver for clear signaling of reset events without watchdog timer or manual reset functionality.

Operating temperature ranges from -40°C to +85°C, making it suitable for industrial-grade environments. The reset active time of 280 ms guarantees stable communication and proper reset timing. Its compact size, with dimensions 3 mm length, 1.4 mm width, and 1 mm height, fits small surface-mount PCB layouts.

The product is designed to operate between 1.1 V minimum and 5.5 V maximum supply voltages, allowing flexibility across different power domains. This model, APX803-26SAG-7, belongs to the APX803 series known for robust power supply supervision and microprocessor reset capabilities.

Applications include power supply supervision in microcontroller and microprocessor systems, portable battery-operated equipment, multiple output power supplies, and various industrial and consumer electronics. The device helps prevent erratic operation, data corruption, or damage by timely resetting the system during undervoltage conditions.

This voltage supervisor performs precise monitoring of supply voltage at 2.63 V threshold. The 3-pin SOT-23 form factor enables easy surface mounting on PCB assemblies. No manual reset or watchdog timer functions are integrated, focusing purely on voltage supervisory tasks.

Extended operating temperature from -40°C to +85°C supports diverse industrial applications. Active low output driver signals reset events in a straightforward manner. Supply voltage operation range from 1.1 V to 5.5 V provides compatibility with various power systems.

Compact device dimensions allow its use in size-sensitive electronic designs. Microprocessor supervisory feature guards against undervoltage and power fail scenarios.
