NJM2670E3 belongs to PMIC (Power Management IC) - Motor Drivers, Controllers. PMIC is designed to manage the power flow between the sensor, battery, and other devices by controlling the voltage, current and limited power supplies, allowing the system design to be more energy efficient. NJM2670E3 is a high-efficiency and low-noise Charge Pump IC with a built-in DC-DC converter that provides low voltage operation, high output current and high efficiency. This IC also includes a wide range of features such as soft start, UVLO, thermal shutdown, and large onboard memory.

NJM2670E3 has many applications in automotive and industrial fields, such as power converters, battery-powered motors, wireless charging systems, and energy harvesting. In the automotive field, this IC is used for engine control, powertrain control, and oil pump control, while in the industrial field, it is used for electric motor control, sensors, and robotic devices.

The working principle of NJM2670E3 is that two switched-capacitor voltage converter circuit is used to generate the output voltage, which is higher than the input voltage. The two switched-capacitor generator is connected in parallel, yet with different output voltages and switching frequencies. These two outputs are then combined and smoothed by a filter. With the help of an internal DC-DC converter and a boosting circuit, the output voltage can be regulated, and the output current can be controlled to be higher than the input current.

NJM2670E3 is exceptionally efficient, with energy efficiency of over 94%. Compared to other integrated charge pumps, its noise level is much lower and its power dissipation is reduced. The soft start feature allows a steady start-up of the IC and the UVLO (Under Voltage Lock Out) feature prevents the IC from working at dangerously low voltage levels, thus ensuring every device’s safety. Thermal shut down is also available to protect the device from getting too hot and to ensure the best performance. Finally, the IC also offers an onboard memory for storage of parameters and settings.

NJM2670E3 is ideal for power-conscious designs, due to its low voltage operation, high output current, and high efficiency. This IC is widely used in automotive and industrial motor control applications, as well as wireless charging systems, energy harvesting, and IoT devices. The high efficiency and low noise make it an ideal solution for battery-powered designs. Furthermore, the UVLO, thermal shut down, and onboard memory provide robust protection and flexibility for the device.

Overall, NJM2670E3 is a highly efficient, low-noise, and robust IC suitable for many applications, such as automotive and industrial motor control, charging systems, and energy harvesting. Its exceptional efficiency, low noise, and onboard memory make it an ideal solution for battery-powered designs.
