PMIC - Supervisors

The MAX16030TG+ is a power supply supervisor IC with extended temperature range, designed for applications requiring advanced power-up and power-down control of supplies and system reset monitoring. Built with a combination of internal diagnostics and analog monitoring, the MAX16030TG+ helps protect systems from fluctuations while extending battery life.

Application Field of MAX16030TG+

The MAX16030TG+ is suitable for use in a wide range of applications, such as consumer electronics, automotive, and industrial. The most prominent of these is consumer electronics, such as smartphones, tablets, and notebook PCs, due to its robust performance and wide-operating temperature range.

Features of MAX16030TG+

The MAX16030TG+ maintains reliable system operation even under tough environmental conditions, with an extended junction temperature range of -40 to 150°C and an extended input voltage range of 0.75V to 4.6V. It features an integrated watchdog timer with 2-bit programmable timeout, power-on reset circuit with selectable reset active delay, and independent active-high RESET and RESETF outputs. The MAX16030TG+ also integrates two additional low-power channels, allowing up to three independent system reset functions and one additional power-up output.

Working Principles of MAX16030TG+

The MAX16030TG+ is based on a digital power monitoring system with analog input comparison. On power-up, the chip monitors the power supply for faults and initiates an active-high RESET signal if any are detected. Once power has stabilized, the chip continuously monitors the power supply and triggers the RESET or RESETF outputs if an incorrect or desired supply voltage is detected. The MAX16030TG+ also monitors its watchdog timer, issuing a reset signal if the timer reaches its programmed timeout. The timers are programmable through SYSET and SOLARET pins.

Conclusion

The MAX16030TG+ is an integrated power supervisor IC, built with extended temperature range and a full suite of internal diagnostics, reset functions, and watchdog timer. Suitable for use in a wide range of applications, the MAX16030TG+ helps protect systems from fluctuations while extending battery life. With its advanced power-up and power-down control, system reset monitoring, and rich features, the MAX16030TG+ is an ideal choice for any application requiring reliable and robust power management.
