- RESET: Active-low push-pull reset output
- VCC: Supply voltage input
Functional Features
- Power-On Reset: Generates a reset signal when the supply voltage rises above the reset threshold voltage.
- Low-Voltage Monitoring: Monitors the supply voltage and asserts the reset signal if it falls below the reset threshold voltage.
- Manual Reset Input: Allows an external signal to assert the reset signal, overriding the internal monitoring circuitry.
Advantages and Disadvantages
