Product details
Overview
MPC17511EP from NXP Semiconductors (formerly Freescale) is a monolithic H-bridge motor driver IC designed for bidirectional control of micro brushed DC motors in portable battery-powered systems. It delivers 1.0 A continuous / 3.0 A peak output current, supports 2.0–6.8 V motor supply, features 0.46 Ω (typ) RDS(ON), integrated charge pump, shoot-through protection, and TSWITCH output for external MOSFET control - used in single-lens camera autofocus actuators.
For engineers reviewing the MPC17511EP datasheet, MPC17511EP pinout, MPC17511EP application, or MPC17511EP equivalent, key selection criteria include PWM frequency support up to 200 kHz, undervoltage lockout behavior, tri-state bridge control logic, thermal performance at 65°C ambient, and compatibility with 3.0 V/5.0 V MCU interfaces.
Technical Context
The MPC17511EP integrates dual high-side and low-side drivers with independent input/output circuitry, enabling four discrete operating modes: Forward, Reverse, Brake, and Tri-state (Open). Its internal charge pump generates gate drive voltage for N-channel MOSFETs without requiring external boost components.
It implements hardware-level shoot-through current protection and an undervoltage detection circuit that disables outputs below ~2.0 V VM supply. Logic inputs accept 2.7–5.7 V, supporting direct interfacing with 3.0 V and 5.0 V MCUs without level shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 1.0 A continuous / 3.0 A peak - sustains motor stall and acceleration loads without external heatsinking in portable enclosures. |
| RDS(ON) (typ) | 0.46 Ω per channel - minimizes conduction loss and self-heating during PWM-driven operation at 200 kHz. |
| Motor Supply Range | 2.0 V to 6.8 V - matches Li-ion, Li-poly, and dual-AA battery configurations across portable optical modules. |
| PWM Frequency Support | Up to 200 kHz - enables high-resolution speed/torque control while avoiding audible noise in camera focus mechanisms. |
| Logic Voltage Range | 2.7 V to 5.7 V - ensures robust interface with both 3.3 V and 5.0 V microcontrollers without external translators. |
| Operating Ambient Temp | –20°C to +65°C - validated for consumer-grade optical disc drives and compact camera modules with passive thermal management. |
Pinout & Package
Package: 24-pin QFN (4 mm × 4 mm, 0.5 mm pitch), thermally enhanced with exposed die pad (PGND/LGND connected internally).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN3 | Bridge Control Inputs | Three logic inputs configure forward/reverse/brake/tri-state modes; IN1/IN2 control H-bridge, IN3 enables TSWITCH output. |
| OUTA / OUTB | H-Bridge Outputs | Direct connection points to motor terminals; each capable of sinking/sourcing 1.0 A continuously with 0.46 Ω (typ) on-resistance. |
| VM | Motor Supply Input | Primary power rail for H-bridge switches; accepts 2.0–6.8 V; internal UVLO triggers below ~2.0 V. |
| VDD | Logic Supply Input | Supplies internal logic and charge pump; operates from 2.7–5.7 V; decoupled via C1H/C1L. |
| TSWITCH | External MOSFET Driver | Open-drain output for controlling auxiliary load (e.g., lens solenoid or LED bias); driven by IN3 logic state. |
| EN | Enable Input | Active-high global enable; forces all outputs to high-impedance when low; supports system-level power gating. |
| PGND / LGND | Power & Logic Ground | Separate ground pins minimize switching noise coupling into logic circuits; tied together externally at single point. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Generates gate drive voltage for internal N-channel MOSFETs - eliminates need for external boost capacitor or high-side driver IC. |
| Shoot-Through Protection | Hardware logic prevents simultaneous high-side/low-side conduction - avoids destructive shoot-through current during mode transitions. |
| Tri-State Bridge Control | Independent IN1/IN2 states allow open-circuit (coast) mode - critical for precise positioning in camera lens actuation. |
| Undervoltage Lockout (UVLO) | Disables outputs when VM drops below ~2.0 V - prevents erratic motor behavior during battery depletion in portable devices. |
| TSWITCH Output | Dedicated open-drain driver controlled by IN3 - enables synchronized control of auxiliary components (e.g., IR LED or solenoid) alongside motor motion. |

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 | Higher 1.2 A continuous current; dual H-bridge (2 channels); no TSWITCH output; requires external bootstrap caps. | Better suited for dual-motor systems (e.g., robot wheels); lacks dedicated auxiliary driver for solenoids/LEDs. | Select when needing two independent bridges or higher current per channel; not drop-in due to different pinout and control logic. |
| DRV8833 | Lower 1.5 A peak current; dual H-bridge; no charge pump (uses external bootstrap); no UVLO or shoot-through protection. | Targeted at cost-sensitive, low-power applications where protection features are managed externally. | Choose for simpler, lower-cost designs where system-level fault handling is implemented in MCU firmware. |
Compared with TB6612FNG and DRV8833, the MPC17511EP offers unique integration of TSWITCH output and charge pump-based gate drive in a single-channel configuration - optimizing board space and BOM count for single-motor optical modules requiring auxiliary load control.

FAQ
What is the maximum PWM frequency supported by the MPC17511EP?
The MPC17511EP supports PWM input frequencies up to 200 kHz. This capability enables high-resolution motor speed and torque control while avoiding audible noise - especially valuable in camera autofocus and optical disc drive applications. The internal driver stages and gate charge management are optimized for stable switching at this frequency without excessive power loss or thermal rise in the 24-pin QFN package.
Does the MPC17511EP require external components for gate driving?
No, the MPC17511EP does not require external components for gate driving. It integrates a charge pump circuit that generates the necessary gate drive voltage for its internal N-channel MOSFETs. This eliminates the need for external bootstrap capacitors or high-side driver ICs, simplifying layout and reducing BOM count - a key advantage in compact portable designs using the MPC17511EP.
What protection features are built into the MPC17511EP?
The MPC17511EP includes hardware-level shoot-through current protection and undervoltage lockout (UVLO). The shoot-through circuit prevents simultaneous conduction of high-side and low-side FETs during state transitions. UVLO disables all outputs when VM falls below approximately 2.0 V, preventing erratic motor behavior during battery depletion - both features are fully integrated and require no external configuration in the MPC17511EP.
Can the MPC17511EP drive motors from a 3.3 V logic supply?
Yes, the MPC17511EP accepts logic inputs from 2.7 V to 5.7 V, making it fully compatible with 3.3 V microcontrollers. Its IN1, IN2, IN3, and EN pins operate reliably at 3.3 V logic levels without level shifters. This interoperability is confirmed in the Freescale MPC17511 fact sheet and enables direct interface with common 3.3 V MCUs in designs using the MPC17511EP.
What is the function of the TSWITCH pin on the MPC17511EP?
The TSWITCH pin on the MPC17511EP is an open-drain output controlled by the IN3 input signal. It provides a dedicated driver for external loads such as lens solenoids, IR LEDs, or auxiliary actuators - enabling synchronized operation with motor motion. Unlike the main H-bridge outputs, TSWITCH is not current-limited internally and must be used with an external current-limiting resistor or transistor when driving higher-current loads in systems based on the MPC17511EP.
