Power management integrated circuit (PMIC) is one of the most commonly used components since mostly electronic devices need to be able to operate under power constraints. It is a kind of circuit to provide the power source for particular devices. PMIC can be divided into supervisors, power switches, power regulators, converters and other categories. The supervisor is a kind of integrated circuit employed to monitor power system, which is a key part of power infrastructure and stability of any device.

One of the most popular supervisors is RT9818C-36GVL. RT9818C-36GVL is an advanced reset circuit designed for OLED display application. It provides several functions, such as power-on reset generation, delay reset, watch-dog timer and system wake up functions.

In terms of application field, RT9818C-36GVL is usually applied in various mobile electronic devices with OLED display, such as mobile phones, digital cameras etc. The reset circuit of RT9818C-36GVL takes an smart low-power architecture to enable fast power-up and low frequency dynamic voltage scaling. By turning off NMOS switches, the reset circuit can reduce the operating current down to 0.5μA, while meeting the reset requirements of different OLED display. Additionally, the operating frequency of TNreset and watchdog is adjustable.

In terms of working principle, RT9818C-36GVL is responsible for monitoring voltage and temperature of the device and will reset if any one of these exceptions is larger than normal. It works in the following steps: Firstly, it remembers the standard value of power up time. Secondly, it decide when to be power off or going to sleep. Thirdly, it monitors the surrounding temperature and voltage, then set the wake-up timer accordingly; if the wake-up timer matches the internal standard wake-up timer value, the device will wake up and reset. Finally, RT9818C-36GVL will give out the reset signal when the temperature or voltage is beyond the normal range.

In conclusion, RT9818C-36GVL is a kind of PMIC supervisor with low-power architecture, which is applicable to various OLED display mobile electronic devices. Its working principle is to monitor the temperature and voltage and reset when it is beyond the normal range. RT9818C-36GVL will be a great solution for power system design.
