Monolithic Power Systems Inc. MP62160DH-LF-P

Overview

MP62160DH-LF-P from Monolithic Power Systems is a single-channel, active-low enable, current-limited power distribution switch with integrated 85mΩ MOSFET, 2A continuous load capability, 2.8A typical current limit, and output discharge function. It operates from 2.7V–5.5V input and delivers robust over-current and thermal protection for USB power rails and portable system hot-swap circuits.

For engineers reviewing the MP62160DH-LF-P datasheet, MP62160DH-LF-P pinout, MP62160DH-LF-P application, or MP62160DH-LF-P equivalent, key selection criteria include its 8ms FLAG deglitch time, reverse current blocking, under-voltage lockout (1.95V threshold), and MSOP8E package thermal resistance (θJA = 55°C/W) for compact board-level power control.

Technical Context

The MP62160DH-LF-P implements a precision current-limit architecture using internal sense-amplifier feedback to enforce constant-current mode at ≥2.8A trip level, with thermal shutdown triggered at 140°C junction temperature and 20°C hysteresis. Its open-drain FLAG pin asserts after an 8ms deglitch window to reject transient overloads.

It integrates an internal discharge resistor (250Ω) across OUT–GND activated during disable or UVLO, ensuring rapid output capacitor discharge (<10ms for 100μF). The device supports reverse current blocking and features 90μA quiescent current in active state and 1μA in shutdown.

Key Specifications

Pinout & Package

FAQ

What is the exact EN pin logic polarity for MP62160DH-LF-P?

The MP62160DH-LF-P uses active-low enable: the switch turns ON when EN voltage is ≤0.8V (logic low) and turns OFF when EN is ≥2.0V (logic high). This is confirmed in the Ordering Information table and Pin Functions section of the Rev. 1.0 datasheet, distinguishing it from the MP62161 variant which is active-high.

Does MP62160DH-LF-P require an external pull-up on the FLAG pin?

Yes - FLAG is an open-drain output and requires an external pull-up resistor (typically 10kΩ to 5V or VCC) to generate a valid high-level signal during normal operation. The datasheet specifies I_{FLAG_OFF} ≤1μA at V_FLAG=5.5V, confirming the need for external biasing to ensure proper logic-level translation to MCU GPIOs.

Can MP62160DH-LF-P safely drive a 100μF output capacitor?

Yes - the datasheet specifies turn-off time (T_off) and discharge behavior explicitly for C_L=100μF and R_L=5Ω, measuring 10ms turn-off and full discharge within <10ms via the internal 250Ω path. No external discharge circuitry is needed, and inrush current remains within the 2.8A current limit during startup.

What is the thermal shutdown recovery behavior?

After thermal shutdown triggers at T_J = 140°C, the device remains latched off until junction temperature falls to approximately 120°C due to the 20°C hysteresis (T_{J_HYS}). Recovery is automatic and does not require cycling EN or VIN - verified in the Thermal Protection section and Absolute Maximum Ratings table.

Is the MSOP8E package of MP62160DH-LF-P lead-free and RoHS compliant?

Yes - the "-LF" suffix explicitly denotes lead-free and RoHS-compliant packaging, confirmed in the Ordering Information footnote stating "For RoHS Compliant Packaging, add suffix –LF". The device also meets halogen-free requirements per MPS Quality Assurance documentation.

How does the 8ms FLAG deglitch time improve system reliability?

The 8ms deglitch window filters out brief overloads such as capacitive inrush (e.g., plugging a 10μF load) that would otherwise falsely trigger fault reporting. This avoids unnecessary system resets or log entries, and is implemented internally - eliminating need for external RC filters or firmware debouncing delays.
