Monolithic Power Systems Inc. MP62160DH-LF-Z

Overview

MP62160DH-LF-Z from Monolithic Power Systems is a single-channel, active-low enable, current-limited power distribution switch with 2A continuous load capability, 2.8A typical current limit, 85mΩ R_DS(on), and integrated output discharge function. It operates from 2.7V to 5.5V input and delivers robust over-current and thermal protection in portable USB power rail management.

For engineers reviewing the MP62160DH-LF-Z datasheet, MP62160DH-LF-Z pinout, MP62160DH-LF-Z application, or MP62160DH-LF-Z equivalent, this device is selected for precise current limiting, fast fault flag response (8ms deglitch), reverse current blocking, and compact MSOP8E packaging in space-constrained hot-swap and USB power-distribution designs.

Technical Context

The MP62160DH-LF-Z implements a precision current-limiting architecture using internal sense-FET feedback to maintain constant output current at ~2.8A during overload, entering thermal shutdown only if sustained dissipation exceeds θ_JA = 55°C/W limits. Its active-low EN pin directly interfaces with low-voltage logic controllers without level shifting.

It integrates an open-drain FLAG pin with 8ms deglitch timing to suppress false OCP assertions, while its 250Ω internal discharge path actively bleeds external output capacitance within milliseconds after disable-eliminating need for external discharge circuitry in battery-backed or sequencing-sensitive systems.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable continuous current for MP62160DH-LF-Z at +85°C ambient?

The MP62160DH-LF-Z maintains 2A continuous current capability up to +85°C ambient temperature in the MSOP8E package, validated by thermal characterization with θ_JA = 55°C/W and junction temperature limited to 150°C. Derating is not required within this range per datasheet Figure 5.

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

Yes-FLAG is an open-drain output and requires an external pull-up resistor (typically 10kΩ to 5V or V_IN) to generate a valid logic-high state when no fault is present. The datasheet specifies I_{FLAG_OFF} ≤ 1μA, ensuring minimal current draw during normal operation.

Can MP62160DH-LF-Z be used with 2.5V input voltage?

No-MP62160DH-LF-Z has a minimum input voltage of 2.7V per absolute maximum ratings and UVLO threshold (1.95V turn-on). At 2.5V, the device remains in under-voltage lockout and will not enable, even if EN is asserted.

How does the output discharge function behave during thermal shutdown?

The discharge function remains active during thermal shutdown: when EN is low or UVLO is triggered, the internal 250Ω path connects OUT to GND regardless of thermal state, ensuring safe capacitor bleed-down even during fault conditions.

Is the exposed thermal pad on MP62160DH-LF-Z electrically isolated?

No-the exposed pad on the MSOP8E package is internally connected to GND and must be soldered to a PCB ground plane. It serves both thermal dissipation and electrical grounding functions; floating or connecting it to another net violates datasheet layout requirements and compromises thermal performance.

What is the turn-off time when disabling MP62160DH-LF-Z into a 100μF load?

Measured from 50% EN deassertion to 10% V_OUT, the turn-off time is 10ms into a 100μF load with 5Ω series resistance (per datasheet Table 1, condition #8). This includes both MOSFET gate discharge and output capacitor discharge through the internal 250Ω path.

Does MP62160DH-LF-Z support reverse current flow from OUT to IN?

No-it provides reverse current blocking: when disabled or when V_OUT > V_IN, the internal MOSFET body diode is reverse-biased and the control circuit holds the FET off, limiting reverse leakage to ≤0.2μA (per datasheet Table 1, I_REV).
