NXP Semiconductors MPC17511AEV

Overview

MPC17511AEV from Freescale Semiconductor is a monolithic 1.0 A H-bridge motor driver IC designed for portable DC motor control in space-constrained applications. It operates from 2.0 V to 6.8 V, delivers 1.0 A continuous/3.0 A peak output current, features integrated charge pump and cross-conduction suppression, and supports PWM up to 200 kHz - used in CD-ROM head positioners, camera focus motors, and shutter solenoids.

For engineers reviewing the MPC17511AEV datasheet, MPC17511AEV pinout, MPC17511AEV application, or MPC17511AEV equivalent, key selection considerations include its 16-pin VMFP package, 0.46 Ω typical R_DS(ON), undervoltage shutdown thresholds (VDD < 2.0 V, VM < ~2.0 V), and four-mode operation (Forward/Reverse/Brake/Tri-State).

Technical Context

The MPC17511AEV integrates a voltage-tripling charge pump (VCRES ≈ 3×VDD) to enable high-side gate drive without external boost supplies, supporting efficient 200 kHz PWM switching. Its internal logic includes cross-conduction suppression with timing-controlled dead-time and dual undervoltage detection circuits for both VDD (1.5–2.5 V threshold) and VM supply rails.

It implements four discrete operating modes via EN, IN1, and IN2 inputs per truth table: Forward (IN1=H/IN2=L), Reverse (IN1=L/IN2=H), Brake (IN1=H/IN2=H), and Tri-State (IN1=L/IN2=L). GIN controls an auxiliary high-side gate driver output (GOUT) for external MOSFETs with ≤500 pF C_ISS.

FAQ

What is the maximum continuous output current rating for the MPC17511AEV?

The MPC17511AEV is rated for 1.0 A continuous output current per channel at TA = 25°C with proper PCB thermal design. Its 150 °C/W junction-to-ambient thermal resistance in the 16-pin VMFP package requires adequate copper pour to sustain this current without exceeding TJ(max) = 150°C. Peak current capability is 3.0 A for 10 ms pulses at 200 ms intervals, as specified in the Absolute Maximum Ratings table.

Does the MPC17511AEV require external capacitors, and if so, what values and types are recommended?

Yes, the MPC17511AEV requires three external ceramic capacitors: two 0.1 μF bucket capacitors (C1, C2) connected across C1H/C1L and C2H/C2L, and one 0.1 μF reservoir capacitor (C3) on the CRES pin. All must be X7R or better dielectric, rated ≥16 V, and placed within 2 mm of their respective pins with short, direct traces to minimize parasitic inductance - critical for stable charge pump operation up to 200 kHz PWM.

How does the MPC17511AEV implement undervoltage protection, and what are the trip thresholds?

The MPC17511AEV implements dual undervoltage lockout: VDD detection triggers shutdown when logic supply drops below 1.5–2.5 V (typical 2.0 V), and VM detection activates when motor supply falls below ~2.0 V. Both cause outputs to enter high-impedance state. Recovery is automatic once supply rises above threshold; no reset pin or external intervention is needed. This protects against erratic behavior during battery sag or power sequencing faults.

Can the MPC17511AEV drive a bipolar stepper motor, and if so, how many ICs are required?

Yes, the MPC17511AEV can drive one phase of a bipolar stepper motor. A complete two-phase bipolar stepper requires two MPC17511AEV ICs - one per phase - with coordinated IN1/IN2 control to generate full-step, half-step, or microstepping waveforms. Each IC independently manages its phase current and braking, leveraging the device's 1.0 A continuous rating and fast 0.55 μs propagation delay for precise timing alignment.

What is the function of the GIN and GOUT pins on the MPC17511AEV, and when should they be used?

The GIN pin controls the GOUT output: when GIN = LOW, GOUT provides a level-shifted high-side gate drive signal referenced to VCRES (~12–13.5 V); when GIN = HIGH, GOUT is pulled to LGND. GOUT is intended to drive external high-side N-channel MOSFETs (≤500 pF C_ISS) for applications needing higher voltage/current than the internal H-bridge can deliver - such as driving solenoids or custom motor windings beyond 1 A.
