NXP Semiconductors MPC17510EJ

Overview

MPC17510EJ from NXP Semiconductors is a monolithic H-bridge motor driver IC designed for portable DC motor control in digital/SLR cameras and similar compact electronics. It delivers 1.2 A continuous output current (3.8 A peak), operates from 2.0 V to 15 V supply, features 0.45 Ω typical R_DS(on), and supports PWM up to 200 kHz with integrated charge pump and cross-conduction protection.

For engineers reviewing the MPC17510EJ datasheet, MPC17510EJ pinout, MPC17510EJ application, or MPC17510EJ equivalent, key selection criteria include its 24-pin TSSOPW package, TTL/CMOS-compatible 5.0 V logic interface, four-mode operation (Forward/Reverse/Brake/Tri-state), undervoltage shutdown on both VM and VDD, and internal gate-drive level shifting for high-side MOSFET control.

Technical Context

The MPC17510EJ implements a SMARTMOS-based H-bridge with integrated charge pump (voltage tripler) generating ~13 V gate drive from 5 V VDD, enabling full enhancement of internal N-channel MOSFETs. Its control logic accepts parallel 5.0 V inputs (IN1, IN2, EN, GIN) with hysteresis and supports dynamic braking via simultaneous high-level IN1/IN2 or low-level EN.

It integrates shoot-through prevention via timing-controlled cross-conduction suppression, dual undervoltage detection (VM threshold ≈4.0–6.0 V, VDD threshold ≈1.5–3.5 V), and thermal shutdown. The GOUT pin provides level-shifted gate drive for external high-side switches, while CRES, C1H/C1L, and C2H/C2L pins interface with external charge pump capacitors (0.001–0.1 μF).

FAQ

What is the maximum continuous output current rating for the MPC17510EJ?

The MPC17510EJ is rated for 1.2 A continuous DC output current per channel at TA = 25 °C with proper PCB thermal design (37 mm × 50 mm Cu area). Peak current capability reaches 3.8 A for 10 ms pulses at 200 ms intervals. This rating assumes operation within the specified ambient temperature range (−30 °C to +65 °C) and adherence to thermal resistance limits (RθJA = 120 °C/W).

Does the MPC17510EJ require external charge pump capacitors, and if so, what values are recommended?

Yes, the MPC17510EJ requires three external capacitors: one reservoir capacitor on CRES (0.001–0.1 μF) and two bucket capacitors - one pair on C1H/C1L and another on C2H/C2L (each 0.1 μF typical). These capacitors enable the internal voltage tripler to generate sufficient gate drive voltage (~13 V) for full enhancement of the internal N-channel MOSFETs, especially at low VDD.

How does the MPC17510EJ implement undervoltage protection, and what are the threshold voltages?

The MPC17510EJ features dual undervoltage lockout: VDDDET triggers at 1.5–3.5 V (typical 2.5 V) and VMDET at 4.0–6.0 V (typical 5.0 V). When either supply drops below its threshold, the H-bridge outputs enter high-impedance state to prevent erratic motor behavior or shoot-through. Recovery is automatic once voltage rises above the hysteresis band - no reset pulse required.

Can the MPC17510EJ drive external high-side MOSFETs, and how is this configured?

Yes, the MPC17510EJ supports external high-side drive via the GOUT and GIN pins. When GIN is driven LOW, GOUT outputs a level-shifted gate signal referenced to VCRES (≈13 V), capable of driving MOSFETs with CISS up to 500 pF. When GIN is HIGH, GOUT is pulled to LGND. This feature extends the device's capability beyond its internal 1.2 A limit for specialized motor or solenoid loads.

What are the four operating modes of the MPC17510EJ, and how are they selected?

The MPC17510EJ supports Forward, Reverse, Brake, and Tri-state (high-impedance) modes. Selection is determined by the logic states of IN1, IN2, and EN per the truth table: Forward (EN=H, IN1=H, IN2=L), Reverse (EN=H, IN1=L, IN2=H), Brake (EN=H, IN1=H, IN2=H), and Tri-state (EN=H, IN1=L, IN2=L). EN=LOW forces all outputs to high-Z and disables the charge pump.
