PMIC (power management integrated circuit) is a general term for integrated circuits that affect or control the power distribution, power conversion, power conversion efficiency and power quality of an electronic system. The S-80122CNMC-JKHT2U is a family of automotive-grade power management ICs (PMICs) for automotive applications such as engine control unit (ECU) applications and occupant detection system (ODS) applications. The S-80122CNMC-JKHT2U provides many features such as low power startup voltage, high accuracy voltage measurement, hardware protection and software recovery, quick response to transient input current events, per-channel over-temperature protection and thermal shutdown, etc.

The S-80122CNMC-JKHT2U falls into the category of PMIC Supervisors. PMIC Supervisors are power management solutions employed to monitor and protect power sources when voltage, temperature or current exceed pre-defined limits. These PMICs provide an integrated, low-cost, low-power method of protecting and managing complex power system design.

The S-80122CNMC-JKHT2U is suitable for a variety of applications including automotive ECU and ODS. As an automotive ECU application, it can be used for controlling the fuel injection system and the ECU can be monitored and protected from voltage overshoots, under-voltage and any sudden input current events. As a safety-critical application such as in an ODS, the S-80122CNMC-JKHT2U can provide the system with protection from temperature overshoots and any sudden current events. The device also enables quick response to transient temperature, current and voltage changes. The device can also be used as an over-voltage protection and power sequencing function, to ensure that the power supply is distributed in the right order.

The S-80122CNMC-JKHT2U is based on the principles of voltage and temperature supervisors. The voltage supervision monitors the voltage levels of the power sources against pre-defined voltage thresholds and triggers an action if the voltage is either too high or too low. The threshold values are set by two resistors on the device, which can be configured in the system to the required voltage levels. The temperature supervision monitors the temperature of the system and triggers an action if the temperature exceeds a certain pre-defined threshold, which is adjusted by a resistor connected to the device.

In terms of functionality, the S-80122CNMC-JKHT2U provides several features such as low operating power consumption, low power startup, temperature monitoring and protection, hardware protection and software recovery, high accuracy voltage measurement and per-channel over-temperature protection. The device also features a low current which allows the system to enter low-power state when silent periods occur. This feature helps to reduce the overall power consumption of the system. The device also has an exposed thermal pad for heat dissipations, which is suitable for most power management applications. The device further has a high immunity to Electrostatic Discharge (ESD) and Electromagnetic Interference (EMI).

The S-80122CNMC-JKHT2U is a family of automotive-grade power management ICs (PMICs) for automotive applications such as engine control unit (ECU) applications and occupant detection system (ODS) applications. It is an excellent example of a PMIC supervisor, providing many features such as low power startup voltage, high accuracy voltage measurement, hardware protection and software recovery, quick response to transient input current events, per-channel over-temperature protection and thermal shutdown, etc. It also features low power consumption and a low current feature which allows the system to enter low-power state when necessary. Additionally, it provides robust protection against ESD and EMI.
