Product details
Overview
MPC17511AEVEL from NXP Semiconductors (formerly Freescale) is a monolithic H-bridge motor driver IC designed for portable electronics, delivering 1.0 A continuous and 3.0 A peak current to small DC or bipolar stepper motors. It operates from 2.0 V to 6.8 V supply, features integrated charge pump and cross-conduction suppression, and supports PWM control up to 200 kHz - used in CD-ROM head positioners, camera focus actuators, and shutter solenoids.
For engineers reviewing the MPC17511AEVEL datasheet, MPC17511AEVEL pinout, MPC17511AEVEL application, or MPC17511AEVEL equivalent, key selection criteria include its 16-pin VMFP package, 0.46 Ω typical RDS(ON), undervoltage shutdown thresholds at 1.5–2.5 V on VDD and VM, and four-mode operation (Forward/Reverse/Brake/Tri-State).
Technical Context
The MPC17511AEVEL integrates a voltage-tripling charge pump (CRES ≈ 3×VDD), level-shifting gate drivers, and logic-controlled shoot-through prevention via timing-based cross-conduction suppression. Its dual-stage protection includes independent undervoltage detection on both VDD (logic) and VM (motor) rails, forcing outputs into high-impedance state when either falls below threshold.
Control is implemented through parallel TTL/CMOS-compatible inputs (IN1, IN2, EN, GIN) with hysteresis, enabling direct MCU interfacing at 3.0 V or 5.0 V logic levels. The GOUT pin provides a level-shifted high-side gate drive signal for external MOSFETs, while internal H-bridge outputs (OUT1/OUT2) switch between VM and PGND based on truth-table-defined input states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VM) | 2.0 V to 6.8 V - enables battery-powered operation from single Li-ion or dual alkaline cells. |
| Continuous Output Current | 1.0 A - sufficient for driving small DC motors in optical drives and autofocus mechanisms. |
| RDS(ON) (typ.) | 0.46 Ω - minimizes conduction loss and thermal rise at rated load in 16-pin VMFP package. |
| PWM Frequency Support | Up to 200 kHz - allows high-resolution speed/torque control without audible noise in sensitive applications. |
| VDD Undervoltage Threshold | 1.5–2.5 V - ensures reliable logic reset before power collapse affects control integrity. |
| Logic Compatibility | 3.0 V / 5.0 V TTL/CMOS - eliminates need for level shifters when interfacing with common microcontrollers. |
| Thermal Resistance (θJA) | 150 °C/W - defines maximum power dissipation (830 mW at TA = 25°C) in VMFP package without heatsink. |
Pinout & Package
Package: 16-pin Very Thin Mini Flat Package (VMFP), Pb-free (EV suffix), 37 × 50 × 1.6 mm body with exposed pad not specified for thermal bonding per datasheet Rev. 5.0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| C2L | Charge Pump Bucket Capacitor 2 (negative) | Connects to negative terminal of external 0.1 μF capacitor for second stage of voltage tripler. |
| C1H | Charge Pump Bucket Capacitor 1 (positive) | Connects to positive terminal of first bucket capacitor; forms part of internal charge pump network. |
| C1L | Charge Pump Bucket Capacitor 1 (negative) | Connects to negative terminal of first bucket capacitor; critical for stable gate-drive voltage generation. |
| VM | Motor Drive Power Supply | Main power input (2.0–6.8 V); supplies current path for H-bridge outputs OUT1/OUT2. |
| VDD | Logic Supply | Provides 2.7–5.7 V to internal logic, charge pump control, and input buffers; monitored for UVLO. |
| IN1 / IN2 | Direction Control Inputs | Define H-bridge state (Forward/Reverse/Brake/Tri-State) per truth table; CMOS-compatible with hysteresis. |

| LGND | Logic Ground | Reference for VDD and digital inputs; must be low-impedance connected to PGND. |
| GIN | Gate Driver Input | Controls GOUT output: LOW enables high-side gate drive signal; HIGH pulls GOUT to LGND. |
| OUT1 / OUT2 | H-Bridge Outputs | Drive motor terminals; switch between VM and PGND depending on input logic combination. |
| PGND | Power Ground | Return path for motor current; requires separate low-impedance PCB trace from LGND before connection point. |
| GOUT | External Gate Driver Output | Level-shifted signal for driving external high-side MOSFET; supports CISS ≤ 500 pF. |
| CRES | Charge Pump Reservoir | Output of internal tripler (~12–13.5 V); connects to reservoir capacitor or external gate supply via current-limiting resistor. |
| C2H | Charge Pump Bucket Capacitor 2 (positive) | Positive terminal of second bucket capacitor; completes second stage of charge pump voltage multiplication. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | 2-channel 1.2 A H-bridge in SSOP24; lower RDS(ON) (0.35 Ω), no integrated charge pump (requires external VBIAS). | Requires external gate bias supply; better suited for fixed 5 V systems with higher efficiency demands. | Select when higher current capability and lower conduction loss outweigh added external component count. |
| VN772K | Single-channel high-side/low-side driver (1.5 A) with SPI interface and diagnostics; no H-bridge topology or charge pump. | Designed for automotive load switching with fault reporting; lacks direction control logic and integrated bridge. | Choose only for non-reversible loads requiring embedded diagnostics and CAN-compatible control, not for bidirectional motor control. |
Compared with TB6612FNG and VN772K, the MPC17511AEVEL uniquely integrates a voltage-tripling charge pump and cross-conduction suppression in a compact VMFP package, making it optimal for space-constrained portable designs needing self-contained 3.3 V/5 V MCU interfacing without external bias rails.

FAQ
What is the maximum continuous motor current supported by the MPC17511AEVEL?
The MPC17511AEVEL supports 1.0 A continuous motor current at TA = 25°C in its 16-pin VMFP package. This rating assumes proper PCB layout with adequate copper area for heat dissipation and operation within the 2.0 V to 6.8 V VM supply range. Peak current capability is 3.0 A for short durations (10 ms pulses at 200 ms intervals), as specified in the Absolute Maximum Ratings table.
Does the MPC17511AEVEL require external capacitors, and if so, what values are recommended?
Yes, the MPC17511AEVEL requires three external capacitors: two 0.1 μF bucket capacitors (C1, C2) connected across C1H/C1L and C2H/C2L, and one 0.1 μF reservoir capacitor (C3) connected from CRES to PGND. These values are validated in the Electrical Characteristics tables and ensure stable operation of the internal voltage-tripling charge pump across temperature and supply variations.
How does the undervoltage lockout function on the MPC17511AEVEL?
The MPC17511AEVEL implements dual undervoltage lockout: one on VDD (logic supply) with threshold 1.5–2.5 V, and another on VM (motor supply) with unspecified but functional threshold. When either rail drops below its respective threshold, the output stage enters high-impedance state to prevent erratic switching. Recovery is automatic once voltage rises above threshold, resuming operation per current input logic state.
Can the MPC17511AEVEL drive a bipolar stepper motor, and how is it configured?
Yes, the MPC17511AEVEL can drive one phase of a bipolar stepper motor. A pair of MPC17511AEVEL devices is required - one for each winding - with coordinated IN1/IN2 inputs from a common MCU to generate full-step or half-step sequences. Each device independently controls current direction and magnitude via PWM on its respective EN pin, enabling precise microstepping when combined with current-sensing feedback.
What is the purpose of the GIN and GOUT pins on the MPC17511AEVEL?
The GIN pin controls the GOUT output: when GIN is logic LOW, GOUT delivers a level-shifted high-side gate drive signal referenced to CRES voltage (~12–13.5 V); when GIN is HIGH, GOUT is pulled to LGND. This allows the MPC17511AEVEL to drive an external high-side MOSFET while retaining internal H-bridge control over OUT1/OUT2, extending voltage/current capability beyond the IC's native ratings.
