ON Semiconductor MAX810RTRG Microprocessor Reset Circuit
The ON Semiconductor MAX810RTRG is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a crucial function in ensuring system integrity by resetting the microprocessor during power-up, power-down, and brown-out conditions. With its precision factory-trimmed threshold voltage, the MAX810RTRG guarantees reliable operation by maintaining system sanity during fluctuations in the power source.
This device comes in a tiny SOT-23 package, making it an ideal choice for space-constrained applications. The MAX810RTRG features an active low reset output, which remains asserted until the supply voltage reaches the reset threshold level and maintains stability for the reset active time. This ensures that the microprocessor is held in the reset state until conditions are suitable for safe operation, thereby preventing any erroneous functioning that could arise from unpredictable power levels.
Key features of the MAX810RTRG include:
- A precise factory-set V<sub>CC reset threshold voltage that caters to a broad range of supply voltages.
- Low supply current, making it suitable for power-sensitive applications.
- An active low RESET output, which is guaranteed to be in the correct state for V<sub>CC down to 1V.
- Immunity to short V<sub>CC transients, ensuring stable operation under brief power glitches.
- Wide operating temperature range, accommodating various environmental conditions.
The MAX810RTRG is commonly used in computers, controllers, intelligent instruments, portable/battery-powered equipment, and other microprocessor-based systems where reliable reset functionality is essential. Its ease of integration and minimal external components requirement simplifies design and reduces overall system costs.
ON Semiconductor's commitment to quality ensures that the MAX810RTRG provides the performance and reliability required for modern electronic systems, making it a trusted choice for designers looking to enhance system stability and robustness.
