Today, power management integrated circuits (PMICs) are used to optimize and regulate the power supply in a given application, such as LED (light-emitting diode) driver applications. Properly designed PMICs can be used to control and reduce power usage in terms of current, voltage, and frequency.

The SP7685ER-L/TR PMICs from STMicroelectronics is a series of linear LED drivers designed for the power management of LEDs with 8-ballchip light source. This family of devices features an integrated current controller, temperature sensing, and overvoltage protection that operate within the industry-standard space constraints.

The SP7685ER-L/TR PMICs\'s application field involves lighting solutions that require a precisely regulated voltage, current, or temperature range. In LED lighting designs, this PMIC series is suitable for systems that need a brighter light output or that can handle a greater number of LED components in a limited system area.

The SP7685ER-L/TR PMICs have a wide operating voltage range of 4.5V to 40V and a wide output current range of 1mA to 1A. The integrated thermal sensor provides temperature protection and accuracy. The internal current control loop provides a precise output current with minimum voltage drop, resulting in improved light output efficiency.

The SP7685ER-L/TR PMICs also feature an overvoltage protection mode that prevents an excessive voltage from being applied to the LED, thus protecting it from damage due to voltage spikes. Additionally, the integrated current control loop helps maintain the output current within the specified limits, reducing power consumption and noise in the system.

As a linear LED driver, the SP7685ER-L/TR PMICs provide accurate current and voltage control, enabling designers to optimize overall system performance. The combination of sub-500μA current consumption and temperature protection offers improved lighting solutions while reducing operating and thermal management costs.
