PMIC - Supervisors are integrated circuit devices that integrate a variety of power functions, including power on/off control, power supply sequencing, power monitoring, and system supervision into one package. Supervisors provide safety and security to the end user’s systems by monitoring voltages and currents, performing a set of power-on and power-off tasks, and providing fault supervision and reset capabilities. One popular supervisor is the APX803L-42SA-7 – a 3.6V to 5.5V supervisor with Push-Pull Rail-to-Rail output.

APX803L-42SA-7 is a low-power 3.6 V to 5.5 V supervisor that features a push-pull rail-to-rail output. The IC works in a wide temperature range of -40°C to +85°C. The output pin is rated for a current handling of 1 mA and can be driven from either an open-drain or open-collector design. The supervisor provides two reset outputs, two active output and two status output pins. The outputs can be programmed to act as reset, active, or status pins depending on the user’s application needs.

The APX803L-42SA-7 has multiple application fields including micro-controllers, LC, CRT displays, and other embedded systems. The supervisor has been designed to fit in the density-constrained applications and supports a wide temperature range. The two reset outputs are both active-low signals that are driven by the internal power-on reset (POR) and power supply reset (PSR) circuits. The active outputs can be used for configuring power-up and power-down sequences, while the status outputs can be used for monitoring device health or as an indication of fault conditions.

The APX803L-42SA-7 supervisor uses an internal compared circuit that measures the input voltage against a programmable threshold. This circuit will generate an active-low reset signal if the voltage drops below its threshold. The reset output duration is programmable with an external capacitor and resistor. The supervisor features an ‘auto retake’ circuit, which eliminates false positives generated by small power glitches.

The APX803L-42SA-7 supervisor is a low-power supervisor that can be used in a wide variety of applications. It offers two active low reset outputs and two status outputs that can be used to configure power-up and power-down sequences, monitor device health, or to indicate fault conditions. The supervisor has an internal compared circuit that measures the input voltage against a programmable threshold and the reset output duration is programmable with an external capacitor and resistor. The auto retake circuit ensures that small power glitches do not trigger false positives. The supervisor operates in a wide temperature range and has been designed for density-constrained applications.
