Diodes Incorporated APX803L-29SA-7 Voltage Supervisor IC

The APX803L-29SA-7 is a highly precise micro-power voltage supervisor component designed by Diodes Incorporated, engineered to maintain system integrity by monitoring the supply voltage of microprocessors (µP) and digital systems. This device is an essential component for applications that require reliable operation under varying voltage conditions, making it an ideal choice for portable and battery-powered equipment.

This voltage supervisor IC features a fixed threshold voltage of 2.93V, which is particularly suited for 3.3V powered systems. When the monitored voltage falls below the factory-set threshold, the APX803L-29SA-7 asserts a reset signal, which remains asserted until the voltage recovers to an acceptable level, ensuring the system has adequate time to restore to a stable state before resuming operation.

The APX803L-29SA-7 boasts an impressive low supply current of just 10µA (typical), contributing to the overall power efficiency of the system it is integrated into. The device comes in a small SOT-23 package, which is highly advantageous for space-constrained applications, providing a compact solution without compromising on performance.

Key features of the APX803L-29SA-7 include:

• Fixed threshold voltage: 2.93V suitable for 3.3V systems
• Low supply current: 10µA (typical) for power-sensitive applications
• Asserted reset output down to 1V for guaranteed system reset
• Minimum 140ms reset timeout delay ensuring system stability
• Available in a small footprint SOT-23 package
• Operating temperature range from -40°C to +85°C for extreme environments

Applications that can benefit from the APX803L-29SA-7 include:

• Portable and battery-powered devices
• Microprocessor/microcontroller systems
• Computers and embedded systems
• Industrial controls
• Medical monitoring equipment
• Automotive electronics

With its precision voltage monitoring and low power consumption, the APX803L-29SA-7 from Diodes Incorporated is a reliable and efficient solution for safeguarding sensitive electronic systems from the perils of under-voltage conditions.
