LED Driver IC datasheet and documents for MIC2843YMT-TR
LED Driver IC Overview
The MIC2843YMT-TR is a six-channel linear white LED driver IC manufactured by Microchip Technology. It operates with an input voltage range of 3V to 5.5V and provides a constant output current of 20mA per channel. The device supports PWM dimming at a frequency of 500kHz and features a supply current of 1400uA. Packaged in a 10-pin TDFN EP (MLF-10) surface-mount case, it is designed for direct battery-driven applications in mobile devices.
LED Driver IC Feature Summary
- Six independent current sink channels for driving white LEDs
- Linear regulation architecture for high efficiency
- Supports PWM dimming control for brightness adjustment
- Designed for direct battery operation without boost converters
LED Driver IC Applications
- Portable display backlighting in mobile devices
- Keypad backlighting systems
- Camera flash applications
LED Driver IC Procurement Notes
Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the package type matches the 10-pin TDFN EP footprint required for the design. Check for obsolescence status as distribution data may vary. Ensure compatibility with the target system's input voltage range of 3V to 5.5V before procurement.
LED Driver IC Selection Notes
Select this component for applications requiring multiple white LED channels driven directly from a single-cell lithium-ion or polymer battery. It is suitable where space constraints favor a compact TDFN package over larger solutions. Consider the linear topology limitations regarding thermal dissipation if the voltage differential between input and LED forward voltage is significant.
LED Driver IC Part Context
This part belongs to the MIC2843Y series of LED drivers from Microchip Technology. It is distinct from the MIC284 temperature sensor family, sharing only the base number prefix. The device is engineered specifically for portable electronics, offering a simplified solution for multi-channel LED management compared to complex switching drivers.
LED Driver IC Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications against potential alternatives carefully.
