PMIC - Supervisors

The MAX6385XS18D5-T supervisor is a powerful field-proven device that provides system monitoring and power-on reset functions in one small 8-pin package. It is an ideal choice for keeping low power systems stable with easy system integration and exceptional reliability.

The MAX6385XS18D5-T supervisor uses precision voltage-monitored circuits and logic to detect when the input power supply is outside its specified levels. When an out-of-tolerance event occurs, the supervisor’s logic output generates a reset signal that clears the memory and forces any devices associated with the power supply to reset and re-establish communication.

The MAX6385XS18D5-T has two supply monitor inputs (VCC and CORE). When either one of these supplies falls below the minimum trippoint or rises above the maximum trippoint, the device will generate a reset to the component. The reset is active-low and can assert at any voltage above the reset threshold and below the maximum reset threshold.

The MAX6385XS18D5-T also includes a pulse-width selectable delay circuit (DF) which provides an adjustable time window for the supervisor to distinguish between a transient glitch and a legitimate power failure. This adjustable delay feature prevents spurious power supply reset on power system disturbances that do not need to be cleared, such as brief interruptions caused by supply ripple, line overshooting, or glitches from other components.

The MAX6385XS18D5-T is ideal for a variety of applications such as mobile phones, security system, and portable electronic devices. Its on-chip diagnostic features significantly reduce board space and simplify system design. In addition, its precise monitoring accuracy offers precise and consistent system operation in a wide range of operating temperatures.

The MAX6385XS18D5-T supervisor provides system designers with a highly integrated and efficient solution to managing device and system power-on reset and system monitoring functions. Engineers can easily select the monitoring configuration to meet the system performance requirements, depending on the application. With its low profile, small package, and wide operating temperature range, the MAX6385XS18D5-T supervisor is the ideal choice for portable electronic systems, offering reliability and ease of integration.
