MAX16832AASA/V+T

LED Driver IC Overview

The MAX16832AASA/V+T is a high-brightness LED driver IC featuring an integrated power MOSFET and high-side current sense amplifier. It operates as a step-down (buck) converter with a fixed switching frequency of 2 MHz. The device supports PWM dimming for precise brightness control and accepts supply voltages between 6.5 V and 65 V. It delivers up to 700 mA output current per channel in an 8-pin SOIC-EP package.

LED Driver IC Feature Summary

• Integrated high-side current sensing eliminates external shunt resistors
• Fixed 2 MHz switching frequency enables compact passive component selection
• Supports analog and PWM dimming methods for flexible control

LED Driver IC Applications

• Automotive exterior lighting systems
• High-brightness general illumination fixtures
• Industrial LED lighting arrays

LED Driver IC Procurement Notes

Verify the specific suffix 'V' against the manufacturer's official datasheet to confirm temperature range and package variant accuracy. Confirm RoHS compliance status directly with Analog Devices or authorized distributors, as '+T' indicates tape-and-reel packaging. Ensure the ordering part number matches the exact electrical specifications required for your design.

LED Driver IC Selection Notes

Select this component when a buck topology is required for driving high-voltage LED strings from a wide input voltage range. The integrated MOSFET simplifies thermal management compared to discrete solutions. Verify that the 2 MHz frequency aligns with EMI constraints and that the 700 mA current rating meets the target LED load requirements without exceeding junction temperature limits.

LED Driver IC Part Context

This part belongs to the Maxim Integrated MAX16832 family of high-brightness LED drivers. These devices are designed for automotive and industrial applications requiring reliable, high-efficiency LED control. The series typically includes variants with different packages and temperature ratings, sharing core functionality such as integrated power switches and current regulation.

LED Driver IC Replacement Considerations

Check for direct pin-compatible alternatives within the MAX16832 family, such as the MAX16832AASA+ (without the '/V' suffix), if temperature range differences are acceptable. Cross-reference with other Maxim buck LED drivers like the LT3964 series if interface or current requirements differ significantly.
