MAX6388XS43D5-T

PMIC (Power Management Integrated Circuit) is a special type of integrated circuit that is used to manage the performance of other electronic circuits. In particular, Supervisors, or voltage supervisory circuits, are used to ensure that a predetermined voltage level is maintained for the duration of a circuit’s operation. One of the most prolific supervisors on the market is the MAX6388XS43D5-T, a voltage supervision IC from Maxim Integrated that provides fixed voltage and reset outputs for circuits that require power management.

The MAX6388XS43D5-T is suitable for a variety of applications, including systems that employ power rails and systems that require remote reset. In particular, it is designed for use in any environment that experiences extreme fluctuations in power, such as automotive, industrial, or battery-powered applications. Additionally, the MAX6388XS43D5-T is ideal for audio and data systems that require automated power control, as it can be used to enable/disable components.

In addition to its wide range of applications, the MAX6388XS43D5-T is also well-suited to a variety of voltages. As such, it is available with both “High Signal” (Vcc ≤ 5.0V) and “Low Signal” (Vcc ≤ 3.3V) inputs. Additionally, the MAX6388XS43D5-T’s adjustable turn-on and turn-off thresholds make it ideal for use with a variety of voltage levels, ranging from 1.5V to 3.3V.

The MAX6388XS43D5-T’s basic working principle is straightforward. When the voltage at its input is below the “turn on” threshold, the voltage is passed directly to its output. If the voltage at its input is above the “turn off” threshold, the MAX6388XS43D5-T will cut off power to its output. This makes it well-suited for applications where a valuable component can be damaged due to an overvoltage condition.

The MAX6388XS43D5-T features an integrated Watchdog Timer that can be configured to monitor the status of the circuit’s input voltage. If the input voltage falls below the turn-on threshold for longer than the time interval set by the Watchdog Timer, the MAX6388XS43D5-T will generate a reset signal to restart the circuit. This Watchdog Timer ensures that any situation where the circuit is not providing power as expected is addressed in a timely manner.

The MAX6388XS43D5-T is also equipped with an open-drain Manual Reset input that can be used to enable manual resets. This Manual Reset input allows the system designer to trigger a reset by simply tying the input to ground. This advantageous feature makes the MAX6388XS43D5-T suitable for use in circuits where manual reset is essential.

In addition to its onboard Manual Reset input, the MAX6388XS43D5-T also features an onboard Enable/Disable function. This function can be used to enable/disable the supervisor during a system’s operation, providing for further control over the circuit’s power management. The Enable/Disable functionality can be controlled via either a logic input or an external control signal. This ensures that the supervisor is able to provide safe and reliable protection even when the system’s operating conditions change.

The MAX6388XS43D5-T is a highly reliable and easy to implement supervisor circuit. Its application field ranges from simple power rails to complex systems with voltage-monitored power control and manual reset inputs. Additionally, its adjustable turn-on and turn-off thresholds, along with its onboard Watchdog Timer and Enable/Disable functions, make the MAX6388XS43D5-T an ideal solution for systems that require reliable voltage management.
