NXP Semiconductors MPC17511AEPR2

Overview

MPC17511AEPR2 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 DC motor current with 0.46 Ω typical R_DS(ON) at 25°C, operating from 2.0 V to 6.8 V supply, and supporting PWM control up to 200 kHz in camera focus motor and CD-ROM head positioner applications.

For engineers reviewing the MPC17511AEPR2 datasheet, MPC17511AEPR2 pinout, MPC17511AEPR2 application, or MPC17511AEPR2 equivalent, key selection criteria include integrated charge pump operation, cross-conduction suppression logic, undervoltage shutdown thresholds on both VDD and VM, and compatibility with 3.0 V/5.0 V TTL/CMOS logic interfaces.

Technical Context

The MPC17511AEPR2 integrates a voltage-tripling charge pump to generate ~13 V gate drive (VCRES) from a 5.0 V VDD supply, enabling full enhancement of internal N-channel MOSFETs without external high-side drivers. Its internal shoot-through protection uses timing-controlled cross-conduction suppression logic between complementary half-bridge switches.

It supports four discrete operating modes-Forward, Reverse, Brake (both outputs low), and Tri-State (high-impedance)-controlled via EN, IN1, IN2, and GIN inputs. The device features dual undervoltage detection circuits: one on VM (motor supply) and one on VDD (logic supply), each forcing output tri-state when threshold is breached.

FAQ

What is the maximum PWM frequency supported by the MPC17511AEPR2?

The MPC17511AEPR2 supports pulse-width modulation up to 200 kHz, as confirmed in its Electrical Characteristics table (Table 5). This high-frequency capability enables smooth motor control with minimal audible noise and precise torque regulation in applications like camera focus actuators. The device maintains stable switching performance across its full 2.0–6.8 V VM supply range without requiring external gate drivers.

Does the MPC17511AEPR2 require external capacitors for its charge pump?

Yes, the MPC17511AEPR2 requires four external ceramic capacitors (C1H, C1L, C2H, C2L) and one reservoir capacitor (CRES) to operate its internal voltage-tripling charge pump. Per the datasheet, typical values are 0.1 µF for all five capacitors. These components are mandatory for generating the ~13 V gate drive voltage (VCRES) needed to fully enhance the internal N-channel MOSFETs.

How does the MPC17511AEPR2 handle undervoltage conditions?

The MPC17511AEPR2 implements dual undervoltage lockout: one on VDD (logic supply, threshold 1.5–2.5 V) and one on VM (motor supply, threshold ~4.5 V). When either supply falls below its respective threshold, the output stage enters high-impedance tri-state mode to prevent erratic behavior or partial turn-on. Both circuits automatically resume normal operation once voltage recovers above threshold.

What is the function of the GOUT pin on the MPC17511AEPR2?

The GOUT pin on the MPC17511AEPR2 provides a level-shifted gate drive signal referenced to VCRES (not ground), enabling direct control of an external high-side N-channel MOSFET. When GIN is low, GOUT outputs VCRES; when GIN is high, GOUT pulls to LGND. This feature extends the H-bridge topology beyond the internal outputs, supporting custom motor configurations or higher-current external switches.

Is the MPC17511AEPR2 pin-compatible with other variants in the 17511A family?

No, the MPC17511AEPR2 (24-pin QFN) is not pin-compatible with the MPC17511AEV (16-pin VMFP) variant. Their pin counts, layouts, and terminal assignments differ significantly-e.g., VM is distributed across four pins in the QFN but is single-ended in the VMFP, and CRES serves as pre-driver power supply in QFN versus charge pump reservoir in VMFP. PCB layout and schematic must be redesigned for migration.
