Introduction of PMIC - Supervisors

PMIC - Supervisors are devices used to monitor and control external devices on circuits. They are often used in microcontrollers and processors, monitoring circuit voltages and other parameters on the microcontroller. Supervisors continuously check the status of various circuits, and if something is amiss, they send an alert signal in order to protect other electronic components.

MAX709TCPA+ Application Field and Working Principle

The MAX709TCPA+ is an ultra-low-power supervisor device designed to monitor circuit parameters and protect circuits. The device monitors the supply voltage, power supply voltage and power-on-reset. It is available in a small 2 mm x 2 mm 8-pin TDFN (Thin Dual Flat No-Lead) package and is ideal for use in portable, battery-powered applications. The MAX709TCPA+ is a supervisor device that monitors the supply voltage, power-on-reset threshold, and power-on reset status all in one efficient unit. It has two independent supply voltage monitors (VCCMON and VDDMON) that can detect VCC, VSS or VDD voltage. The device also features a push-pull output, which can be used to generate reset signals or control external devices on the circuit. The output is a logic voltage level that is below VCC when the reset pin is active. The device also has an output enable pin, which reduces power consumption when the functions are not required.

Working Principle of MAX709TCPA+

The MAX709TCPA+ supervisor performs several functions: it monitors the supply voltage and generates a reset if the voltage drops below a predetermined threshold, it monitors power-on reset threshold and generates a reset when the voltage drops below a preset value, and it also monitors power-on reset status and generates an alert signal if the status does not match the expected result. The MAX709TCPA+ supervisor can be used to detect undervoltage (UV) or overvoltage (OV). It is triggered by the VCCMON and VDDMON pins when the voltage is below the VCC or VDD pin threshold. The device can also detect an active power-on-reset signal. When this occurs, the RESET pin is asserted (active) and an active-low reset signal is generated at the output.The device also features an output enable pin which can be used to reduce power consumption when the functions are not required. The device also has a low shutdown current when the output enable pin is active and the VCC voltage is below the VCC threshold. The MAX709TCPA+ is available in 8-pin TDFN (Thin Dual Flat No-Lead) and is fully specified for operation over the -40°C to +85°C temperature range.

Conclusion

In conclusion, the MAX709TCPA+ is an ultra-low-power supervisor device designed to monitor circuit parameters and protect circuits. It is available in a small 2 mm x 2 mm 8-pin TDFN (Thin Dual Flat No-Lead) package and is ideal for use in portable, battery-powered applications. The device is capable of monitoring supply voltages, reset thresholds, and reset status. It also features an output enable pin, which reduces power consumption when the functions are not required.
