PMIC - LED Drivers
The MAX16814CAUP+T is an advanced LED driver IC developed by Maxim Integrated, a leader in the analog and mixed signal IC industry. This product is a comprehensive, multi-channel LED driver IC with integrated long-term compensation, current regulation, and dimming control. It is designed to drive up to 9 LEDs in a wide variety of lighting applications, such as general lighting fixtures, automotive headlights and taillights, exit signs, industrial and commercial lighting, medical devices, and more.Application Field
The MAX16814CAUP+T is primarily designed for use in driving and dimming LEDs. It is ideal for applications such as low-voltage DC or AC power supply-operated LED lighting, LED signage, and LED lighting for general illumination. It also offers protection features to prevent damage to the LED circuitry from faulty external signals or environmental conditions. The MAX16814CAUP+T is highly suitable for harsh conditions such as automotive, industrial, luminaries, and LED lighting applications. It features over temperature protection to protect the LED from thermal runaway when driving WLEDs, as well as over-voltage protection (OVP) to protect against output voltage spikes. The device is also suitable for automotive lighting applications, offering both CAN bus and analog dimming control. The driver IC is also designed to meet stringent automotive safety requirements, as well as EMC and safety requirements. The IC also offers several performance monitoring functions that enable users to actively monitor the internal operation of the IC. It monitors the voltage and current values of the LEDs, and provides diagnostic feedback that enables the user to take preventive actions in case of a system fault. Working Principle
The MAX16814CAUP+T is a high-performance, high-performance LED driver IC. It is designed with analog control and long-term optimization to drive up to 9 LEDs in a wide variety of application conditions. The IC employs a unique current-sensing architecture and utilizes reference voltage trimming to provide uniform current accuracy and repeatability across multiple channels.The device is powered by either a DC or AC power supply. It is capable of delivering up to 25mA of peak current per channel, allowing for up to 225mA of total peak current for 9 connected channels. The constant-current LED drivers use a series connection to reduce the voltage drop between the supply voltage and the LED voltage. The user can adjust thechannel output current and brightness using the analog dimming control input.To protect the LED driver against faults, the IC also features current regulation, over-temperature, and over-voltageprotection. Current regulation ensures that current flowing through the LED is always within safe limits, while the over-temperature and over-voltage protection prevents damage to the LED circuitry from environmental conditions. Additionally, the thermal protection feature shuts down the LED driver if the temperature exceeds a predetermined level. In conclusion, the MAX16814CAUP+T is an advanced and reliable LED driver IC, suitable for driving and dimming LEDs in a wide variety of lighting applications. It features over-temperature and overvoltage protection, current regulation, and dimming control, while also offering protection against faulty external signals or environmental conditions. The IC is also designed to meet stringent automotive safety requirements, as well as EMC and safety requirements.
