Product details
Overview
MPC17529EVEL 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 3.0 V/5.0 V CMOS-compatible logic inputs, integrated charge pump, and low RDS(on) of 0.7 Ω (typ) at 25 °C - enabling efficient drive in camera lens actuators and optical disk head positioners.
For engineers reviewing the MPC17529EVEL datasheet, MPC17529EVEL pinout, MPC17529EVEL application, or MPC17529EVEL equivalent, key selection criteria include dual-channel independent control, shoot-through protection, undervoltage shutdown, PWM capability up to 200 kHz, and compatibility with 20-pin VMFP packaging for space-constrained portable designs.
Technical Context
The MPC17529EVEL integrates two fully independent H-bridge power stages with on-chip charge pump (VCRES ≈ 3×VDD), pre-driver circuitry, and logic-level shifters. Each bridge supports four operating modes - forward, reverse, brake, and high-impedance - controlled via parallel 5-pin logic interface (IN1A/IN1B/OE/IN2A/IN2B) with OE active-low enable.
It implements hardware-level shoot-through current protection and undervoltage detection (VDDDET = 2.0 V typ), automatically placing outputs in tri-state when VDD drops below threshold. The device uses external 0.1 μF bucket capacitors (C1L/C1H/C2L/C2H) to sustain gate drive voltage for high-side MOSFETs under VM > VDD conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.7 A continuous per channel; sufficient for driving small bipolar stepper motors or dual micro DC motors in portable optics. |
| RDS(on) | 0.7 Ω typical (25 °C); minimizes conduction loss and thermal rise during sustained motor operation. |
| Logic Supply Range | VDD = 2.7–5.6 V; supports direct interfacing with 3.0 V or 5.0 V MCUs without level-shifting. |
| PWM Frequency | Up to 200 kHz; enables precise speed/torque control with minimal audible noise in motion systems. |
| Charge Pump Output | VCRES = 12–13.5 V; ensures full enhancement of high-side MOSFETs even when VM = 6.8 V and VDD = 3.0 V. |
| Undervoltage Threshold | VDDDET = 2.0 V typical; disables outputs before logic becomes unreliable, preventing erratic motor behavior. |
| Thermal Resistance | RθJA = 120 °C/W (on 37 × 50 mm² Cu PCB); defines maximum power dissipation limit under ambient conditions. |
Pinout & Package
Package: 20-pin Very Thin Micro Lead Frame Package (VMFP), Pb-free, exposed pad for thermal management (suffix EV). Dimensions per NXP drawing 98ASA10616D.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Control Circuit Power Supply | Supplies logic and pre-driver circuitry; triggers undervoltage shutdown if <2.0 V. |
| 2–3, 18–19 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. |
| 4 OE | Output Enable (Active Low) | Global disable: pulls all four outputs to high-impedance regardless of input 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 | Power Ground Returns | High-current return paths for motor current; must be tied together with low-inductance layout. |
| 8, 17 VM1/VM2 | Motor Supply Inputs | Accept 2.0–6.8 V motor supply; internally connected - must be shorted on PCB. |
| 9 CRES | Charge Pump Output | Provides ~13 V gate drive to pre-drivers; requires external resistor if externally sourced. |
| 10–13 C2H/C1H/C1L/C2L | Charge Pump Capacitor Terminals | Connect to 0.1 μF ceramic bucket capacitors; critical for sustaining high-side gate voltage. |
| 20 LGND | Logic Ground Reference | Low-noise reference for control logic; separate from PGND to reduce coupling noise. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Eliminates need for external high-voltage supply while enabling full enhancement of high-side MOSFETs up to VM = 6.8 V. |
| Shoot-Through Protection | Hardware-level prevention of simultaneous high-side/low-side FET conduction, avoiding destructive cross-conduction current. |
| Tri-State Mode Support | Four distinct operational states (forward/reverse/brake/high-Z) per channel, enabling precise motor positioning and coasting. |
| Low Quiescent Current | IQVDD ≤ 1.0 mA (no signal); extends battery life in always-on portable applications like autofocus modules. |
| ESD Robustness | ±1500 V HBM; withstands handling and board assembly stress without latch-up or parametric shift. |

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 continuous current (1.2 A), no integrated charge pump (requires external bootstrap or high-side supply). | Better suited for higher-torque DC motors; less suitable for ultra-low-voltage (2.0–3.0 V) battery-powered designs. | Select when motor load exceeds 0.7 A or when external gate drive is acceptable for layout flexibility. |
| DRV8833 | Lower RDS(on) (0.5 Ω typ), but limited VM range (2.7–10.8 V) and no undervoltage shutdown function. | Preferred for cost-sensitive consumer devices where UVLO is managed by system MCU instead of IC. | Choose when system-level supervision replaces IC-level fault protection and lower conduction loss is prioritized. |
Compared with TB6612FNG and DRV8833, the MPC17529EVEL uniquely combines 2.0 V minimum operation, integrated charge pump, and guaranteed UVLO - making it optimal for space-constrained, single-cell Li-ion or alkaline-powered portable motion systems requiring autonomous fault response.

FAQ
What is the maximum motor supply voltage supported by the MPC17529EVEL?
The MPC17529EVEL supports a motor supply voltage (VM) range of 2.0 V to 6.8 V. This upper limit is specified in the Absolute Maximum Ratings table and ensures safe operation of internal power MOSFETs without breakdown. Exceeding 6.8 V risks permanent damage to the device, especially under transient conditions.
Does the MPC17529EVEL require external capacitors for its charge pump operation?
Yes, the MPC17529EVEL requires four external ceramic capacitors: two 0.1 μF bucket capacitors (C1L/C1H and C2L/C2H) and one 0.01 μF capacitor between CRES and GND. These are mandatory for stable charge pump operation and proper high-side gate drive - omission causes incomplete MOSFET turn-on and excessive heating.
Can the MPC17529EVEL drive a bipolar stepper motor using only one H-bridge channel?
No - a bipolar stepper motor requires two full H-bridges (four power switches) to energize both windings with bidirectional current. The MPC17529EVEL provides exactly two independent H-bridges (OUT1A/OUT1B and OUT2A/OUT2B), making it natively compatible with standard 4-wire bipolar stepper motors as shown in Figure 1 of the datasheet.
What happens to the outputs of the MPC17529EVEL when VDD falls below the undervoltage threshold?
When VDD drops below the undervoltage detection threshold (typically 2.0 V), the MPC17529EVEL automatically places all four outputs (OUT1A/OUT1B/OUT2A/OUT2B) into high-impedance state. This prevents unpredictable motor behavior and protects against partial switching that could cause overheating or unintended motion.
Is the MPC17529EVEL pin-compatible with other variants in the MPC17529 family, such as MPC17529EJ?
No - the MPC17529EVEL uses a 20-pin VMFP package (drawing 98ASA10616D), while MPC17529EJ uses a 20-pin TSSOP with exposed pad (drawing 98ASA00887D). Although pin functions and numbering are identical, the physical footprint, thermal pad configuration, and solder reflow profiles differ, requiring separate PCB layouts.
