Product details
Overview
MIC2860-2PYD6-TR from Microchip Technology is a high-efficiency, dual-channel linear white LED (WLED) driver in a 6-lead Thin SOT-23 package, designed for portable display and keypad backlighting. It delivers 30.2 mA per channel with ±0.5% typical current matching, 52 mV dropout at full load, and supports PWM dimming down to 1% duty cycle across 3.0–5.5 V input range.
For engineers reviewing the MIC2860-2PYD6-TR datasheet, MIC2860-2PYD6-TR pinout, MIC2860-2PYD6-TR application, or MIC2860-2PYD6-TR equivalent, key selection considerations include low-noise linear operation, battery-direct drive capability, precise dual-channel current regulation, and compatibility with compact handheld form factors requiring stable WLED brightness control without switching noise.
Technical Context
The MIC2860-2PYD6-TR implements two independent, resistor-programmable current sinks with internal 1.27 V reference, enabling accurate LED current setting via RSET. Its linear architecture eliminates switching losses and EMI by driving LEDs directly from the battery rail-no boost converter or charge pump required.
Control is fully integrated: EN serves as both enable input and PWM dimming interface with 250 Hz minimum frequency support and sub-microsecond rise/fall times (0.7 µs/0.2 µs), while thermal protection operates across –40°C to +125°C junction temperature range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel linear WLED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP3306B-33TR-G1 | Higher dropout (120 mV @ 20 mA), fixed 3.3 V output, no RSET programming | Limited dimming flexibility; lacks 1% PWM support and ±0.5% matching spec | Prefer MIC2860-2PYD6-TR when precise current matching, ultra-low dropout, or resistor-based current tuning is required |
| LM3530UMX/NOPB | I²C interface, 16-step analog + PWM dimming, 32-pin WQFN package | Requires microcontroller communication; larger footprint; higher BOM cost | Choose MIC2860-2PYD6-TR for simpler, lower-cost, pin-efficient designs where I²C control is unnecessary |

FAQ
What is the maximum LED current supported by the MIC2860-2PYD6-TR?
The MIC2860-2PYD6-TR supports up to 30.2 mA per channel when configured with a 9.53 kΩ RSET resistor at 100% PWM duty cycle. Current scales inversely with RSET value-e.g., 19.1 kΩ sets 15.1 mA-and remains stable across –40°C to +125°C junction temperature.
Can the MIC2860-2PYD6-TR drive a single WLED at higher current?
Yes-the MIC2860-2PYD6-TR allows paralleling of D1 and D2 pins to drive one WLED at up to 60.4 mA total current, improving thermal distribution and reducing effective dropout voltage. The datasheet explicitly permits this configuration and confirms matching benefits when outputs are combined.
Does the MIC2860-2PYD6-TR require an external inductor or transformer?
No-the MIC2860-2PYD6-TR is a linear WLED driver and contains no switching elements. It requires only a 1 µF ceramic input capacitor and an external RSET resistor. No inductor, transformer, or charge-pump capacitor is needed, eliminating EMI and simplifying layout.
What is the minimum PWM frequency supported by the MIC2860-2PYD6-TR for 1% dimming?
The MIC2860-2PYD6-TR supports PWM dimming down to 250 Hz for reliable 1% duty cycle operation. At this frequency, the 4 ms period aligns with the device's 4 ms standby-to-shutdown delay, preventing unintended shutdown during the off-phase of low-duty-cycle signals.
Is the MIC2860-2PYD6-TR compatible with lithium-ion battery voltage profiles?
Yes-the MIC2860-2PYD6-TR operates across 3.0 V to 5.5 V input range and maintains regulation with only 52 mV dropout at 30.2 mA, enabling direct connection to single-cell Li-ion (2.7–4.2 V) or Li-poly batteries throughout discharge without intermediate regulation.
