Monolithic Power Systems Inc. MP62130ES-LF-Z

Overview

MP62130ES-LF-Z from Monolithic Power Systems is a single-channel, current-limited power distribution switch with active-low enable, 500mA continuous current rating, 90mΩ R_DS(ON), 2.7V–5.5V input range, and integrated output discharge. It protects USB ports and portable device power rails against overcurrent and thermal faults in smartphone, GPS, and set-top-box applications.

For engineers reviewing the MP62130ES-LF-Z datasheet, MP62130ES-LF-Z pinout, MP62130ES-LF-Z application, or MP62130ES-LF-Z equivalent, key selection criteria include guaranteed 500mA current limit accuracy, 8ms FLAG deglitch timing, reverse current blocking, thermal shutdown at 140°C, and SOIC8 package compatibility with board-level space constraints.

Technical Context

The MP62130ES-LF-Z implements a thermally protected N-channel MOSFET switch with internal current-sense amplifier and deglitched open-drain FLAG output. Its UVLO circuit activates at 1.95V (rising) with 250mV hysteresis, ensuring clean startup under low-input conditions.

Current limiting operates via constant-current mode above 550mA (typ), with trip threshold rising to 1.2A under fast-ramp short-circuit conditions. Output discharge engages automatically during disable or UVLO, using a 100Ω internal path to safely dissipate 1µF–100µF output capacitance.

Key Specifications

Pinout & Package

MP62130ES-LF-Z is housed in an industry-standard SOIC8 package (5.0mm × 6.2mm, 1.27mm pitch), optimized for automated assembly and thermal dissipation (θ_JA = 90°C/W).

FAQ

What is the enable polarity of MP62130ES-LF-Z?

MP62130ES-LF-Z features active-low enable (EN*). The device turns ON when EN* is pulled high (≥2V) and turns OFF when EN* is pulled low (≤0.8V). This matches the "ES" suffix designation in the ordering table and differs from the MP62131's active-high enable.

Does MP62130ES-LF-Z provide reverse current blocking?

Yes. The internal MOSFET structure blocks reverse current flow from OUT to IN when the switch is disabled or during input undervoltage, preventing backfeed into upstream supplies-a critical feature for multi-rail systems and hot-swap applications.

How does the output discharge function operate?

The output discharge activates automatically when EN* is deasserted or input voltage falls below UVLO threshold. A 100Ω internal path discharges external output capacitors, reducing VOUT to <1V within 1ms for 10µF load-eliminating need for external discharge circuitry.

What is the thermal shutdown recovery behavior?

Upon reaching 140°C junction temperature, MP62130ES-LF-Z latches OFF until die temperature cools to approximately 120°C (20°C hysteresis), then resumes normal operation automatically-no external reset required.

Can MP62130ES-LF-Z be used in automotive applications?

No. Its specified operating ambient temperature range is –20°C to +85°C, and it lacks AEC-Q100 qualification. For automotive use, consider MPS's automotive-grade alternatives such as MPQ62130 series, which extend temperature range and add qualification testing.

Is the FLAG pin compatible with 1.8V logic systems?

Yes. FLAG is an open-drain output with ≤0.4V low-level voltage at 5mA sink current, allowing direct interface with 1.8V, 3.3V, or 5V microcontroller GPIOs using appropriate pull-up voltage-no level-shifter needed.

What is the maximum allowable output capacitance?

The datasheet validates operation up to 100µF output capacitance with 11Ω load. Larger values increase turn-on time and inrush stress; for >100µF, verify thermal performance and ensure IN bypass capacitor (≥10µF) is placed within 5mm of the IN pin.
