Disadvantages: - Limited to monitoring voltage levels within the specified range - Requires external resistors for threshold adjustment

Working Principles

The TL7705BID works by comparing the supply voltage with a preset threshold voltage. When the supply voltage falls below the threshold, the internal circuitry triggers the reset output, signaling a system reset. This ensures that the connected microcontrollers or digital devices start from a known state, preventing data corruption or erratic behavior caused by unstable power supply conditions.
