Monolithic Power Systems Inc. MP6215DH-LF-P

Overview

MP6215DH-LF-P from Monolithic Power Systems is a single-channel, active-high enable, current-limited power distribution switch with 90mΩ internal MOSFET, 1.5A continuous output, 2.3A typical current limit, and thermal shutdown protection. It operates from 2.7V to 5.5V input and delivers regulated USB VBUS power in hot-swap applications.

For engineers reviewing the MP6215DH-LF-P datasheet, MP6215DH-LF-P pinout, MP6215DH-LF-P application, or MP6215DH-LF-P equivalent, key selection criteria include accurate 2.3A current limiting, 8ms FLAG deglitch timing, reverse current blocking, and MSOP8-EP thermal performance under sustained 1.5A load.

Technical Context

The MP6215DH-LF-P integrates a precision current-sense amplifier and charge-pump gate driver to maintain constant-current mode during overload, with trip threshold tightly controlled across temperature. Its UVLO (1.95V rising edge) prevents erratic turn-on during brown-out conditions.

Thermal protection activates at 140°C with 20°C hysteresis, enabling automatic recovery above ~120°C. The open-drain FLAG pin reports over-current after 8ms deglitch-excluding UVLO and thermal events-to avoid false fault assertions during transient surges.

Key Specifications

Pinout & Package

MP6215DH-LF-P is housed in an MSOP-8 package with exposed thermal pad (MSOP8E), optimized for PCB heat dissipation (θ_JA = 55°C/W on 4-layer board).

FAQ

What is the maximum continuous output current supported by MP6215DH-LF-P?

The MP6215DH-LF-P supports 1.5A continuous output current at +85°C ambient with proper PCB thermal design (MSOP8E exposed pad soldered to copper plane). Derating is required above this temperature per θ_JA = 55°C/W; at +70°C, full 1.5A is maintained with standard 2oz copper layout.

Does MP6215DH-LF-P provide reverse current protection?

Yes-MP6215DH-LF-P blocks reverse current flow from OUT to IN with only 0.2µA leakage when OUT = 5.5V and IN = GND. This prevents backfeeding into upstream supplies during fault conditions or hot removal, eliminating need for external blocking diodes.

How does the FLAG pin behave during power-up and thermal events?

The FLAG pin is not deglitched during power-up or thermal shutdown-only during over-current events. It asserts LOW after exactly 8ms of sustained overload, but responds immediately to thermal or UVLO faults without delay, enabling fast system-level fault containment.

What is the recommended input capacitor for MP6215DH-LF-P?

A ceramic bypass capacitor of ≥1µF placed directly between IN and GND, adjacent to pins 2/3, is mandatory. For heavy loads (e.g., >1A pulsed), add a bulk electrolytic (≥100µF) on the IN rail to suppress transients and prevent UVLO triggering during inrush.

Can MP6215DH-LF-P be used with 3.3V-only systems?

Yes-MP6215DH-LF-P operates across 2.7V–5.5V, making it fully compatible with 3.3V systems. At 3.3V input, R_DS(on) remains ≤95mΩ, and current limit holds at 2.3A typical; turn-on time increases to 1.7ms due to lower gate drive voltage.

Is the MSOP8E package lead-free and RoHS-compliant?

Yes-the "-LF" suffix in MP6215DH-LF-P explicitly denotes lead-free, RoHS-compliant packaging per JEDEC J-STD-020D. The exposed pad is soldered to PCB ground plane for both thermal and EMI performance, and reflow profile follows standard Pb-free ramp rates (≤3°C/s, peak 260°C).
