Monolithic Power Systems Inc. MP62130ES-LF-P

Overview

MP62130ES-LF-P from Monolithic Power Systems is a single-channel, current-limited power distribution switch with active-low enable, 500mA continuous load capability, 90mΩ R_DS(ON), 2.7V–5.5V input range, and integrated output discharge. It functions as a protected USB VBUS or peripheral power switch in portable electronics, delivering fault-safe load control with thermal shutdown and over-current limiting.

For engineers reviewing the MP62130ES-LF-P datasheet, MP62130ES-LF-P pinout, MP62130ES-LF-P application, or MP62130ES-LF-P equivalent, key selection criteria include guaranteed 500mA current limit accuracy, 8ms FLAG deglitch timing, reverse current blocking, under-voltage lockout (1.95–2.65V), and SOIC8 package compatibility for board-level power sequencing and USB port protection.

Technical Context

The MP62130ES-LF-P implements a thermally protected, current-regulated N-channel MOSFET switch with internal charge pump for gate drive, UVLO circuitry that disables operation below 1.95V, and open-drain FLAG output with 8ms deglitch to suppress transient overcurrent false triggers. Its constant-current mode activates at ≥550mA trip threshold and sustains up to 650mA typical short-circuit current.

It integrates output discharge via a 100Ω internal path activated during disable or UVLO, blocks reverse current from OUT to IN, and features TTL/CMOS-compatible EN input with 0.8V logic low and 2V logic high thresholds. Thermal shutdown triggers at 140°C with 20°C hysteresis, enabling automatic recovery near 120°C.

FAQ

What is the logic polarity of the EN pin on MP62130ES-LF-P?

The EN pin on MP62130ES-LF-P is active-low: the switch turns ON when EN is pulled ≤0.8V (logic low) and turns OFF when EN is ≥2V (logic high). This differs from the MP62131 variant, which uses active-high enable. No external pull-up or pull-down is required unless interfacing with open-drain drivers.

Does MP62130ES-LF-P support reverse current blocking?

Yes-MP62130ES-LF-P blocks reverse current flow from OUT to IN when the input is grounded or disconnected, with measured reverse leakage of ≤0.2µA at V_OUT = 5.5V and V_IN = GND. This eliminates need for external blocking diodes in battery-backup or dual-rail configurations.

How does the FLAG pin behave during power-up?

The FLAG pin remains high (non-asserted) during VIN ramp and EN assertion, with no deglitch filtering applied-ensuring no false fault signals occur at startup. Only sustained overcurrent or thermal faults lasting >8ms will pull FLAG low, providing reliable system-level fault detection without initialization glitches.

What is the maximum allowable continuous power dissipation for MP62130ES-LF-P in SOIC8?

In SOIC8 package, the maximum continuous power dissipation at +25°C ambient is 1.4W, calculated from θ_JA = 90°C/W and T_J(MAX) = 150°C. At 85°C ambient, derated PD_MAX = (150 – 85)/90 ≈ 0.72W-requiring careful layout with thermal vias if operating near full 500mA load at elevated temperatures.

Is output discharge active during under-voltage lockout?

Yes-output discharge engages whenever the device is disabled, including during UVLO (VIN < 1.95V) or EN* deassertion. The 100Ω internal discharge path actively pulls VOUT toward GND, reducing residual voltage to <100mV within ~5ms for a 100µF output capacitor, satisfying IEC 62368-1 touch-safe discharge requirements.

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

No-MP62130ES-LF-P is specified for -20°C to +85°C ambient operation and lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature range support. It is intended for commercial and industrial portable electronics, not under-hood or infotainment systems requiring automotive reliability.

What is the typical turn-off time with a 100µF output capacitor and 11Ω load?

With CL = 100µF and RL = 11Ω, the typical turn-off time (Toff) is 2–10ms, measured from 50% EN* transition to 90% VOUT decay. This controlled fall time prevents abrupt load disconnection that could induce voltage spikes or system brown-outs in sensitive downstream circuitry.
