The MAX817LESA+ is an advanced microprocessor-supervisory device designed principally for use in microprocessor/microcontroller-based systems. It provides an accurate power-on reset and monitors for multiple power-supply voltage inputs. The device is available in the ultra-small SC362-4 and DBV-8 packages.

The MAX817LESA+ is well-suited for microprocessor/microcontroller-based systems that require precise power-on-reset timing and power-supply regulation. It is capable of supplying precise voltage measurement and precise reset timing in these systems. Additionally, the device is capable of monitoring conditions in the system and providing an early warning signal.

The MAX817LESA+ employs a unique voltage clamping circuit to monitor and regulate multiple power-supply voltages. The voltage clamping circuit senses when a power supply voltage is below an adjustable threshold level and sends a reset signal to the microprocessor/microcontroller. This reset signal can be used to shut down or restart the processor or microcontroller.

The MAX817LESA+ also has an operating supply-voltage monitor that helps to detect and correct for brown-out conditions. By sensing the power supply voltage and reporting when it is below a predetermined threshold, it prevents system crashes caused by a sudden power supply drop.

The MAX817LESA+ can also perform preprogrammed functions that can safeguard against system disruptions. One such function is an independent power supply monitor. This monitor senses when the power supply voltage is outside preset limits and can send a signal to a control logic circuit, allowing the system to be put into a safe state.

Another feature of the MAX817LESA+ is programmable power-on delay. This feature allows the user to determine how long the microprocessor/microcontroller waits before it powers up. This allows the user to ensure that when the microprocessor/microcontroller is powered up, all of the other system components are up and running properly.

Finally, this device has an adjustable brown-out voltage threshold and an adjustable reset delay. These two features allow the user to set the voltage at which the power-on reset will occur and the duration before the reset signal is generated. This allows the user to adjust these parameters to make sure that the power-on reset happens at the right time and with the right duration.

In summary, the MAX817LESA+ is an advanced microprocessor/microcontroller-supervisory device with a voltage clamping circuit, operating supply-voltage monitor, independent power supply monitor, and adjustable brown-out voltage threshold and adjustable reset delay. It is the ideal device for applications that require precise power-on-reset timing and power-supply regulation, stage power saving, system reset, and a warning signal when the power supply voltage is low.
