Supervisors, such as the MAX6734KASDD3+, are specifically designed for embedded applications requiring a combination of power supply monitoring, system reset, and system power control. Supervisors help ensure correct system operation and prevent system lock-up due to malfunctions in embedded systems over their lifetime. The MAX6734KASDD3+ is a supervisor that provides system reset, power manager and voltage supervisor functions in a small package.

The MAX6734KASDD3+ has two system reset outputs, and as a system reset supervisor, monitors the supply voltage (VCC) as well as internal voltage. When the VCC or internal voltage drops below the reset threshold voltage, reset output ①which is RST1 goes low, and then resets the system. Reset output ②– RST2 signals increased voltage level. RST2 will goes low when the voltage increases more than the reset threshold up and requires that the rising edge of the reset signal RST2 be longer than the set minimum reset pulse width. The MAX6734KASDD3+ provides better protection against power supply glitches and power sequencing, thus making it an ideal choice for embedded applications.

The MAX6734KASDD3+ also monitors power supply and temperature conditions to protect circuits from over- and under-voltage conditions. If the supply voltage slips below the under-voltage threshold, the MAX6734KASDD3+ sends a reset signal that will put the system in a safe state. If the system is over-heating, the MAX6734KASDD3+ can send a reset signal to shut down the system and prevent damage to circuits. The MAX6734KASDD3+ also has a wide range of voltage levels that can be monitored, ranging from 1.7V to 5.5V.

The MAX6734KASDD3+ also includes a built-in power-manager to provide an optimized power system design while saving board space. It offers an internal power switch, selectable from two to four switch states, and provides over-current protection. The MAX6734KASDD3+ also features two power supply inputs (VIN1 and VIN2), which allows for flexibility in different power sequencing requirements. VIN1 and VIN2 can be used to monitor the system on and off logic and supply power in sequence.

The MAX6734KASDD3+ is designed for high reliability performance in a small package, making it ideal for automotive and industrial applications, and in any application requiring a combination of power supply monitoring, system reset and power control. The MAX6734KASDD3+ helps ensure that systems will reset correctly when faulty power or temperature conditions are detected, and that the system will perform correctly throughout its lifetime.
