Product details
Overview
MPC17529EP from NXP Semiconductors is a monolithic dual H-bridge motor driver IC designed for portable bipolar stepper and brushed DC motor control. It operates from 2.0 V to 6.8 V, delivers 0.7 A continuous output current per channel, features 1.2 Ω max RDS(on) at 25 °C, and supports 3.0 V/5.0 V CMOS-compatible logic inputs - enabling direct interfacing with microcontrollers in camera lens actuators and optical disk drive head positioners.
For engineers reviewing the MPC17529EP datasheet, MPC17529EP pinout, MPC17529EP application, or MPC17529EP equivalent, key selection considerations include its integrated charge pump for high-side gate drive, shoot-through protection, undervoltage shutdown, PWM capability up to 200 kHz, and dual-channel independent control via parallel logic interface.
Technical Context
The MPC17529EP integrates two fully independent H-bridge power stages with internal pre-driver circuitry powered by an on-chip triple charge pump (VCRES ≈ 3×VDD). Each bridge supports four discrete operating modes - forward, reverse, brake, and high-impedance - controlled by dedicated INx/INy logic pairs and a shared active-low OE pin.
Its architecture includes independent VM1/VM2 motor supply inputs, dual external bucket capacitor networks (C1L/C1H and C2L/C2H), separate power grounds (PGND1/PGND2), and logic-level isolation between LGND and PGND. The device implements hardware-level shoot-through prevention and automatic tri-state transition upon VDD falling below 1.5–2.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.7 A DC per channel; sufficient for driving small bipolar stepper coils or 5 V brushed DC motors in portable optics. |
| RDS(on) | 0.7 Ω typ / 1.2 Ω max (source + sink); enables low conduction loss and <1 W dissipation at full load under typical conditions. |
| Logic Supply Range | VDD = 2.7–5.6 V; supports direct connection to 3.0 V or 5.0 V MCU I/O without level-shifting. |
| PWM Frequency | Up to 200 kHz; allows fine-grained speed/torque control and minimizes audible motor noise. |
| Charge Pump Output | VCRES = 12–13.5 V; ensures full enhancement of high-side MOSFETs even when VM > VDD (e.g., VM = 5.0 V, VDD = 3.0 V). |
| Undervoltage Threshold | VDDDET = 1.5–2.5 V; triggers automatic high-impedance shutdown to prevent erratic motor behavior during brownout. |
| Thermal Resistance | RθJA = 120 °C/W; requires PCB copper area ≥37 × 50 mm² for reliable operation at full load. |
Pinout & Package
Package: 20-pin TSSOP with exposed pad (EJ suffix), Pb-free, moisture sensitivity level (MSL) compliant per JEDEC J-STD-020C.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Control Circuit Power Supply | Provides regulated logic supply; triggers undervoltage shutdown if <1.5 V. |
| 2–3, 18–19 IN1A/IN1B/IN2A/IN2B | Bridge Control Inputs | Directly define OUTx state per truth table; all HIGH forces tri-state regardless of OE. |
| 4 OE | Active-Low Output Enable | Drives all outputs to high-impedance when HIGH; overrides INx states. |
| 5, 7, 14, 16 OUT2A/OUT1A/OUT1B/OUT2B | H-Bridge Outputs | Drive motor windings; each pair forms one complete H-bridge (e.g., OUT1A/OUT1B → Channel 1). |
| 6, 15 PGND1/PGND2 | High-Current Power Grounds | Must be tied together on PCB; carry motor return current separately from logic ground. |
| 8, 17 VM1/VM2 | Motor Supply Inputs | Accept 2.0–6.8 V; must be connected externally to common motor rail. |
| 9 CRES | Charge Pump Output | Supplies ~13 V to pre-drivers; requires external RC filter if externally sourced. |
| 10–13 C2H/C1H/C1L/C2L | Charge Pump Capacitor Terminals | Connect external 0.1 μF ceramic capacitors; critical for stable high-side gate drive. |
| 20 LGND | Logic Ground Reference | Reference for VDD and logic inputs; must be isolated from PGND except at single-point star ground. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Triple Charge Pump | Generates VCRES ≈ 3×VDD internally, eliminating need for external high-voltage bias supply. |
| Hardware Shoot-Through Protection | Prevents simultaneous conduction of high- and low-side MOSFETs within each bridge, avoiding destructive current spikes. |
| Independent Dual H-Bridge Control | Enables simultaneous operation of two brushed DC motors or precise 2-phase excitation of one bipolar stepper motor. |
| Low Quiescent Current | IQVDD ≤ 1.0 mA (no signal); extends battery life in always-on portable systems. |
| Fast Switching Performance | tPLH/tPHL ≤ 0.5 μs (8 Ω load); supports high-frequency PWM without significant dead-time distortion. |
Applications

Use Value: Undervoltage shutdown prevents paper jams during battery depletion; shoot-through protection increases system reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual H-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TB6612FNG | Higher 1.2 A continuous current rating; 0.9 Ω max RDS(on); built-in thermal shutdown; no integrated charge pump (requires external bootstrap). | Better suited for higher-torque 3.3 V/5 V brushed DC motors; less ideal for ultra-low-voltage (<3.0 V) battery-powered steppers. | Select when higher current headroom and thermal robustness outweigh need for integrated gate drive. |
| DRV8833 | Lower 1.5 A peak current; 0.5 Ω max RDS(on); integrated current regulation; no charge pump (uses internal LDO for gate drive). | Preferred for cost-sensitive, low-voltage (2.7–10.8 V) applications where precision current limiting is required over wide supply range. | Select when current regulation and smaller footprint are prioritized over maximum efficiency at low VDD. |
Compared with TB6612FNG and DRV8833, the MPC17529EP offers superior gate drive integration for low-VDD operation and tighter RDS(on) matching across channels - making it optimal for compact, battery-powered optical positioning systems demanding consistent dual-channel performance.

FAQ
What is the maximum continuous output current per channel for the MPC17529EP?
The MPC17529EP supports 0.7 A continuous output current per H-bridge channel at TA = 25 °C with proper PCB thermal design. Peak current capability is 1.4 A for short durations (10 ms pulse at 200 ms interval), as specified in the Absolute Maximum Ratings table. Derating is required above 25 °C ambient temperature based on RθJA = 120 °C/W.
Does the MPC17529EP require external charge pump capacitors?
Yes, the MPC17529EP requires four external ceramic capacitors: two 0.1 μF bucket capacitors (C1L/C1H and C2L/C2H) for its internal triple charge pump, plus a decoupling capacitor on CRES. The datasheet specifies 0.01–1.0 μF range for C1L/C1H and C2L/C2H, with 0.1 μF being the recommended typical value for stable VCRES generation.
Can the MPC17529EP drive a bipolar stepper motor using only one H-bridge pair?
No - the MPC17529EP is designed to drive a bipolar stepper motor using both H-bridge channels simultaneously: OUT1A/OUT1B controls Phase A, and OUT2A/OUT2B controls Phase B. Using only one pair would not provide the required two-phase excitation sequence; both bridges must be actively controlled per the truth table and timing diagrams in the datasheet.
What happens to the outputs when VDD drops below the undervoltage threshold?
When VDD falls below the detection threshold (1.5–2.5 V), the MPC17529EP automatically places all four outputs (OUT1A, OUT1B, OUT2A, OUT2B) into high-impedance (tri-state) mode, regardless of INx or OE states. This prevents unpredictable motor behavior during brownout conditions. Normal operation resumes automatically once VDD rises above the threshold and input logic states are re-established.
Is the MPC17529EP pin-compatible with other members of the MPC175xx family?
The MPC17529EP shares identical pinout and package (20-pin TSSOP with exposed pad) with MPC17529EJ, but differs in temperature grade (EP = -40 °C to 105 °C vs. EJ = -20 °C to 65 °C) and qualification. It is not pin-compatible with MPC17529EV (20-pin VMFP), which uses a different footprint and thermal pad configuration despite identical function and pin numbering.
