Product details
Overview
MPC17529EPR2 from NXP Semiconductors is a monolithic dual H-bridge motor driver IC designed for portable electronics, enabling precise bidirectional control of two brush DC motors or one bipolar stepper motor. 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 I/O - used in camera lens positioners and optical disk drive head actuators.
For engineers reviewing the MPC17529EPR2 datasheet, MPC17529EPR2 pinout, MPC17529EPR2 application, or MPC17529EPR2 equivalent, key selection criteria include its integrated charge pump, shoot-through protection, undervoltage shutdown, PWM capability up to 200 kHz, and dual-channel independent control via parallel MCU interface.
Technical Context
The MPC17529EPR2 integrates two fully independent H-bridge power stages with on-chip charge pump (VCRES ≈ 3×VDD) to drive high-side MOSFETs when VM exceeds VDD - critical for efficient operation with 3.0 V logic controlling 5.0 V motor rails. Each bridge supports forward, reverse, brake, and high-impedance modes via dedicated INx/INy and OE inputs.
Its internal architecture separates logic (VDD/LGND), power (VM1/VM2/PGND1/PGND2), and gate-drive (C1L/C1H/C2L/C2H/CRES) domains, with built-in protection including shoot-through prevention, undervoltage lockout (VDDDET = 1.5–2.5 V), and thermal shutdown. Propagation delays are ≤0.5 μs with 8 Ω load, supporting fast PWM commutation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.7 A DC per channel - sufficient for driving small micromotors in camera autofocus and disk drive actuators |
| RDS(on) | 0.7 Ω typ / 1.2 Ω max (25 °C) - minimizes conduction loss and self-heating under load |
| Logic Supply Range | VDD = 2.7–5.6 V - enables direct interfacing with 3.0 V or 5.0 V microcontrollers without level shifters |
| PWM Frequency Support | Up to 200 kHz - allows fine-grained speed/torque control and audible-noise suppression |
| Motor Supply Range | VM = 2.0–6.8 V - accommodates single-cell Li-ion (3.0–4.2 V) and dual-cell alkaline (3.0–6.0 V) battery systems |
| Charge Pump Output | VCRES = 12–13.5 V - ensures full enhancement of high-side MOSFETs even when VM >> VDD |
| Undervoltage Threshold | VDDDET = 1.5–2.5 V - disables outputs before logic becomes unreliable, preventing erratic motor behavior |
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 |
|---|---|---|
| VDD | Control circuit power supply | Provides regulated 2.7–5.6 V to logic core; triggers undervoltage shutdown if below 1.5–2.5 V |
| IN1A/IN1B/IN2A/IN2B | Bridge control inputs | Directly define OUT1A/OUT1B/OUT2A/OUT2B states per truth table; support 3.0/5.0 V logic levels |
| OE | Output enable (active-low) | Global disable: pulls all four outputs to high-impedance regardless of INx states |
| OUT1A/OUT1B/OUT2A/OUT2B | H-bridge power outputs | Drive motor windings; each pair forms one complete H-bridge with ≤1.2 Ω total RDS(on) |
| VM1/VM2 | Motor power supplies | Independent inputs for each bridge's high-side rail; must be tied together externally for shared supply |
| PGND1/PGND2 | High-current power grounds | Return paths for motor current; require low-impedance PCB copper pour to minimize voltage bounce |
| C1L/C1H/C2L/C2H | Charge pump capacitor terminals | Connect external 0.1 μF ceramic capacitors to generate gate drive voltage for high-side MOSFETs |
| CRES | Charge pump output | Supplies ~13 V pre-driver voltage; must not exceed 14 V absolute maximum |
| LGND | Logic ground reference | Separate from PGND to prevent noise coupling into control circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Eliminates need for external high-voltage bias supply - enables 3.0 V MCU to drive 5.0 V motor rails efficiently |
| Shoot-through current protection | Hardware-level prevention of simultaneous high-side/low-side FET turn-on - avoids destructive short-circuit current |
| Tri-state (high-Z) mode | Allows freewheeling or coasting of motors during idle or fault conditions without power dissipation |
| Low quiescent current | IQVDD ≤ 1.0 mA (no signal) - extends battery life in always-on portable devices |
| Fast switching performance | tPLH/tPHL ≤ 0.5 μs - supports high-frequency PWM for smooth torque delivery and reduced acoustic noise |

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 per channel; requires external charge pump capacitors but no CRES pin; 2.7–10 V VM range | Better suited for higher-power motors; lacks integrated undervoltage detection | Select when >0.7 A output or wider VM range is required; verify external charge pump design |
| DRV8833 | Lower 1.5 A peak current; integrated current regulation; no charge pump - limited to VM ≤ VDD + 1 V | Ideal for low-voltage (≤3.6 V) battery systems where gate drive voltage headroom is sufficient | Select for ultra-low-voltage designs (<3.3 V) or when current limiting is preferred over fixed RDS(on) control |
Compared with TB6612FNG and DRV8833, the MPC17529EPR2 uniquely combines integrated charge pump operation, 3.0/5.0 V logic compatibility, and undervoltage shutdown in a compact TSSOP package - making it optimal for space-constrained, battery-powered portable systems requiring robust motor control without external bias circuitry.

FAQ
What is the maximum continuous output current rating for the MPC17529EPR2?
The MPC17529EPR2 supports 0.7 A continuous output current per H-bridge channel at TA = 25 °C, with a peak current capability of 1.4 A for short durations (10 ms pulse at 200 ms interval). This rating assumes proper PCB thermal design with adequate copper area and airflow. Exceeding 0.7 A continuously may trigger thermal shutdown or degrade long-term reliability.
Does the MPC17529EPR2 require external components to operate its charge pump?
Yes, the MPC17529EPR2 requires four external 0.1 μF ceramic capacitors: two for the C1L/C1H and C2L/C2H pairs, plus a decoupling capacitor between CRES and PGND. These capacitors form the flying capacitor network essential for generating the ~13 V gate drive voltage. The datasheet specifies 0.01–1.0 μF as acceptable range, but 0.1 μF is the recommended typical value for stable operation.
Can the MPC17529EPR2 drive a unipolar stepper motor?
No, the MPC17529EPR2 is designed exclusively for bipolar stepper motors and brushed DC motors. Its dual H-bridge topology provides full four-quadrant control (forward/reverse/brake/high-Z) necessary for bipolar winding excitation. Unipolar steppers require center-tapped windings and single-polarity drive - incompatible with the MPC17529EPR2's output configuration and control logic.
What happens to the outputs of the MPC17529EPR2 when VDD drops below the undervoltage threshold?
When VDD falls below the undervoltage detection threshold (1.5–2.5 V), the MPC17529EPR2 automatically forces all four outputs (OUT1A, OUT1B, OUT2A, OUT2B) into high-impedance (tri-state) mode, regardless of INx or OE states. This prevents erratic switching and potential motor runaway. Normal operation resumes automatically once VDD rises above the threshold and input conditions are stable.
Is the MPC17529EPR2 pin-compatible with other members of the MPC175xx family?
No, the MPC17529EPR2 is not pin-compatible with other MPC175xx variants such as MPC17510 or MPC17520. While sharing functional similarities, differences in pin assignment (e.g., CRES placement, PGND count, and OE polarity) and internal architecture prevent direct substitution. Always verify pin functions against the specific device's datasheet - Table 2 in the MPC17529 Rev. 4.0 document confirms the unique 20-pin TSSOP mapping for MPC17529EPR2.
