NXP Semiconductors MPC17511EVEL

Overview

MPC17511EVEL 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 typical R_DS(ON), integrated charge pump, shoot-through protection, and operates up to 200 kHz PWM in optical disc drives and single-lens camera focus mechanisms.

For engineers reviewing the MPC17511EVEL datasheet, MPC17511EVEL pinout, MPC17511EVEL application, or MPC17511EVEL equivalent, key selection criteria include its tri-state bridge control, TSWITCH output for external MOSFET drive, undervoltage detection, 2.7–5.7 V logic compatibility, and VMFP-16 package footprint for space-constrained portable designs.

Technical Context

The MPC17511EVEL implements a fully integrated dual-channel half-bridge with independent high-side and low-side drivers, using an internal charge pump and level shifter to ensure full gate drive across the 2.0–6.8 V motor voltage range. Its four-mode control (Forward, Reverse, Brake, Tri-state) is managed via parallel digital inputs IN1–IN3 and EN, with dedicated CRES and TSWITCH outputs.

It integrates undervoltage lockout (UVLO) at ~2.0 V on VM and ~2.7 V on VDD, plus hardware-based shoot-through prevention that disables both high- and low-side FETs during input transitions. The 200 kHz PWM capability enables precise speed regulation without audible noise in optical actuator applications.

FAQ

What is the maximum continuous motor current supported by the MPC17511EVEL?

The MPC17511EVEL supports 1.0 A continuous output current per H-bridge channel under specified thermal conditions (TA ≤ 65°C, proper PCB copper area). Its 3.0 A peak rating applies for short-duration pulses (e.g., startup torque), but sustained operation above 1.0 A requires careful thermal design and may trigger thermal shutdown.

Does the MPC17511EVEL require external components for basic operation?

Yes-the MPC17511EVEL requires at minimum a 1 µF ceramic capacitor on the CRES pin for charge pump stabilization, appropriate input decoupling capacitors on VDD and VM, and proper grounding of PGND/LGND to a low-impedance plane. No external bootstrap diodes or gate resistors are needed due to its integrated charge pump and level shifter.

Can the MPC17511EVEL operate from a 3.3 V logic supply?

Yes-the MPC17511EVEL accepts 2.7–5.7 V on VDD, making it fully compatible with standard 3.3 V MCU I/O. Its internal logic and charge pump function correctly at 3.3 V, and the TSWITCH output remains functional, enabling seamless integration into modern low-voltage portable systems without level translation.

What protection features are built into the MPC17511EVEL?

The MPC17511EVEL includes hardware-based shoot-through current protection, undervoltage lockout on both VM and VDD rails, thermal shutdown, and output short-circuit detection. These operate autonomously without MCU intervention, ensuring robust motor control even during brown-out or fault conditions.

Is the MPC17511EVEL pin-compatible with other members of the MPC17511 family?

Yes-the MPC17511EVEL shares identical pinout and functionality with the MPC17511EV and MPC17511FS variants. All use the same 16-pin VMFP package and support identical control protocols, allowing direct substitution within the same footprint when thermal or packaging requirements align.
