The AL8821SP-13 is an integrated power module for driving LEDs. It is a member of the PMIC (Power Management IC) family of products and consists of a 9-channel constant current driver, voltage regulator, error amplifier, temperature protection and current monitor. The AL8821SP-13 is ideal for Automotive, industrial, medical, home appliance and backlight applications, providing a high efficiency, robust and cost-effective solution. By using the AL8821SP-13, customers can easily and quickly develop LED applications without the need for manual calculations.
The AL8821SP-13 is optimized for driving high current LEDs with its built-in constant current drivers. Each LED channel is independent and capable of delivering up to 100mA of LED current (50mA at VIN=20V). The current regulation accuracy is +/-3%. With its built-in high voltage power supplies, the AL8821SP-13 can operate from a wide input voltage range from 5V to 40V. The output voltage range is from 6V to 30V, depending on the input voltage. The AL8821SP-13 includes a low dropout voltage regulator, adjustable from 5V to 20V, with a maximum output current of 25mA. A separate GPIO pin is provided for general purpose or as an LED enable pin.
The AL8821SP-13 includes a wide range of built-in protection mechanisms including over-temperature protection, over-current protection, short-circuit protection and ESD protection. It has a low quiescent current (<50uA), which enables longer battery life in portable applications. The AL8821SP-13 is available in a standard SO20 package.
The AL8821SP-13 features an internal error amplifier, which enables it to accurately regulate the current in the LED channels. The internal error amplifier also provides an enable pin, to turn on and off the current, and an external frequency adjustment pin, which can be used to adjust the internal oscillator frequency. This provides flexibility in controlling the current delivered to the LEDs.
The AL8821SP-13 is ideal for driving high current LEDs in applications such as lighting, automotive, home appliances, and backlighting. Its wide input voltage range, high precision current regulation and protection mechanisms make it suitable for use in harsh industrial and automotive environments.
In summary, the AL8821SP-13 is a high performance integrated power module specifically designed to drive high current LEDs. It features an internal error amplifier, over-temperature protection, over-current protection, and short-circuit protection. The AL8821SP-13 is ideal for driving LEDs in an array of applications, providing cost-effective, high accuracy current control and long-term reliability.
