Visão Geral
Description
"DS1233-10" refers to a series of microprocessor supervisory circuits designed by Dallas Semiconductor/Maxim Integrated (now part of Analog Devices). These devices are primarily used to monitor power supply status in embedded systems and microprocessor-based applications. The key function of the DS1233-10 is to ensure the microprocessor is reset when the power supply voltage drops below a specified threshold, thereby preventing erratic system behavior.
Key features of the DS1233-10 include:
1. Voltage Monitoring: It monitors the power supply voltage and triggers a reset when the voltage falls below a predetermined level.
2. Active Low Reset Output: The device asserts a reset signal when the voltage is inadequate, which remains active until the voltage stabilizes and meets the required threshold.
3. Push-button Reset: It often includes a manual reset input, allowing for an external reset signal to be initiated.
4. Precision Voltage Reference: Ensures accurate voltage monitoring and reliable system resets.
These features make the DS1233-10 suitable for applications requiring precise power management and reliability, such as consumer electronics, industrial controllers, and communication devices.

Pinout
The DS1233-10 is a micro-monitor chip designed to monitor the power supply to a microprocessor system. It ensures that the system remains in a reset state during power-up, power-down, and brownout conditions. The DS1233-10 has a 3-pin configuration, and each pin serves the following functions:
1. Pin 1 (GND): This is the ground pin and should be connected to the system ground.
2. Pin 2 (RST): This is the reset output pin. The DS1233-10 holds this pin low whenever the monitored voltage (VCC) is below the specified threshold (4.37V ± 5%). Once the voltage exceeds the threshold, the pin is held low for a minimum of 350 ms after VCC becomes valid.
3. Pin 3 (VCC): This is the supply voltage pin. It monitors the power supply to the microprocessor. If VCC drops below the threshold, the chip asserts the reset signal.
The DS1233-10 helps ensure reliable operation of microprocessor-based systems by providing necessary reset control in response to power supply variations.
