Product Overview: Maxim Integrated MAX705ESA+TG002

The MAX705ESA+TG002 is a highly reliable, precision microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This compact device is engineered to monitor power supplies in µP and digital systems, providing excellent circuit protection and ensuring system integrity. It is a perfect solution for applications that require monitoring of their voltage levels to safeguard against unpredictable power failures, brownouts, and system errors.

Encased in an 8-pin SOIC package, the MAX705ESA+TG002 is ideal for space-constrained applications. It offers key features such as power-on reset control, watchdog timer, and manual reset capability. These functions enable the device to reset a µP during power-up, power-down, and brownout conditions, and to monitor the µP for software failures or malfunctions.

The reset output of MAX705ESA+TG002 remains active for a minimum of 140ms after VCC has risen above the reset voltage threshold, ensuring that the µP has sufficient time to stabilize and start-up correctly. The built-in watchdog timer requires a periodic signal from the µP to prevent it from resetting the µP, thus ensuring regular monitoring of the system's health.

Additionally, the manual reset feature of this device allows for a reset to be triggered with an external button or signal, providing an extra layer of control. The MAX705ESA+TG002 operates over a wide supply voltage range and has a low supply current, making it suitable for battery-operated applications.

Its key specifications include:

• Voltage monitoring to ensure system reliability
• Programmable watchdog timer for system supervision
• Manual reset input for additional system control
• Low power consumption for energy-efficient designs
• Guaranteed reset output valid down to VCC = 1V

Whether it's being used in computers, controllers, intelligent instruments, or portable/battery-powered equipment, the MAX705ESA+TG002 from Maxim Integrated is an excellent choice for designers looking to enhance their system's reliability and performance.
