MAX704RESA+

Power Management ICs (PMICs) provide power sequencing, sequencing and monitoring for integrated circuits, amplifiers and other active components. Supervisors are a special class of PMICs which provide system-level control, enabling and fault protection features by combining voltage monitoring and reset generation. The MAX704RESA+, from Maxim Integrated, is a multi-purpose PMIC supervisor which integrates a precision voltage monitor, a voltage output reset generator and configurable system level controls.

The MAX704RESA+ provides flexibility in a variety of applications as a result of its configurable system level, enabling and fault protection features. It can be used to reset system clocks, peripheral devices, logic, and digital cores. It can also provide system power-up and power-down sequencing, enable monitoring, and configurable system level fault protection.

The multi-functionality of the MAX704RESA+ can be used in a variety of applications, including computing, networking and storage. The device can be used to reset system clocks and peripheral devices in applications such as processors, storage controllers, microcontrollers, DSPs and ASICs. It can provide enable monitoring on power supplies and detect power failures, making it suitable for use in high-reliability applications such as industrial, automotive and embedded systems, as well as in medical equipment.

The MAX704RESA+ features a voltage monitor (VMON) circuit which controls the reset output. The VMON can be programmed to detect a wide range of under-voltage, over-voltage and power failure conditions. The reset output provided by the MAX704RESA+ can be set to active high, active low, or VPOK to indicate the power supply status. In addition, the output can be configured to issue an external interrupt when a fault condition is detected.

The heart of the MAX704RESA+ is its precision voltage monitor (VMON). The VMON continuously monitors system power supply levels and compares them to a programmed threshold. If the system voltage falls below or rises above the programmed threshold, the device will trip and trigger a system reset. The MAX704RESA+ also features an enable input which can be used to enable or disable the device and provides flexibility in how the reset is applied to the system.

The MAX704RESA+ provides flexibility across a wide range of applications thanks to its programmable reset output and enable inputs, as well as its ability to detect a wide range of power failure conditions. Its multi-level power sequencing, sequencing and fault protection features make it suitable for use in a variety of systems and applications, including embedded systems, consumer electronics, automotive and industrial equipment, and medical systems.
