Product details
Overview
MPC17529EV from NXP Semiconductors is a monolithic dual H-bridge motor driver IC designed for portable electronics, delivering 0.7 A DC per channel with 1.2 Ω max RDS(on) at 25 °C, 3.0 V/5.0 V CMOS-compatible logic I/O, and integrated charge pump for high-side gate drive-used in camera lens actuators and optical disk drive head positioners.
For engineers reviewing the MPC17529EV datasheet, MPC17529EV pinout, MPC17529EV application, or MPC17529EV equivalent, key selection criteria include dual-channel independent control, shoot-through protection, undervoltage shutdown, PWM operation up to 200 kHz, and VM supply range of 2.0–6.8 V.
Technical Context
The MPC17529EV integrates two fully independent H-bridge power stages with on-chip charge pump (VCRES ≈ 3×VDD) enabling full enhancement of high-side MOSFETs even when VM exceeds VDD (e.g., VM = 5.0 V, VDD = 3.0 V). Each bridge supports forward, reverse, brake, and high-impedance modes via parallel logic inputs (IN1A/IN1B/IN2A/IN2B) and global OE control.
It features built-in shoot-through current protection, undervoltage detection (VDDDET = 1.5–2.5 V), and thermal shutdown. The device operates across ambient temperatures from –20 °C to +65 °C and uses a 20-pin VMFP package with exposed pad for thermal dissipation (RθJA = 120 °C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.7 A DC per channel; sufficient for driving small bipolar stepper or brushed DC motors in portable imaging systems. |
| RDS(on) | 0.7 Ω typ (source + sink), 1.2 Ω max at 25 °C; enables low conduction loss and minimal self-heating under load. |
| Logic Supply Range | VDD = 2.7–5.6 V; supports direct interface with 3.0 V or 5.0 V microcontrollers without level-shifting. |
| PWM Frequency | Up to 200 kHz; allows fine-grained speed/torque control and minimizes audible motor noise. |
| VM Supply Range | 2.0–6.8 V; compatible with single-cell Li-ion (3.0–4.2 V) or dual-cell alkaline (3.0–6.0 V) battery systems. |
| Charge Pump Output | VCRES = 12–13.5 V; ensures robust gate drive for internal high-side MOSFETs regardless of VDD level. |
| Undervoltage Threshold | VDDDET = 1.5–2.5 V; disables outputs before logic corruption occurs, protecting motor and MCU during brownout. |
Pinout & Package
Package: 20-pin Very Thin Micro Lead Frame Package (VMFP), Pb-free, with exposed thermal pad (suffix EV, drawing 98ASA10616D).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 VDD | Control Circuit Power Supply | Supplies logic core and pre-driver; triggers undervoltage shutdown if < 1.5 V. |
| 2–3, 18–19 IN1A/IN1B/IN2A/IN2B | Bridge Control Inputs | Directly define OUT1A/OUT1B/OUT2A/OUT2B states per truth table; CMOS-compatible, no external pull-ups needed. |
| 4 OE | Global Output Enable | Active-low enable: OE = HIGH forces all four outputs into high-impedance state regardless of input states. |
| 5, 7, 14, 16 OUT2A/OUT1A/OUT1B/OUT2B | H-Bridge Outputs | Drive motor windings; each pair (e.g., OUT1A/OUT1B) forms one complete H-bridge channel. |
| 6, 15 PGND1/PGND2 | High-Current Power Grounds | Separate return paths for each H-bridge; must be tied together on PCB with low-inductance connection. |
| 8, 17 VM1/VM2 | Motor Power Supplies | Input for motor drive voltage; both pins must be shorted externally to share same VM rail. |
| 9 CRES | Charge Pump Output | Provides ~13 V gate drive for high-side MOSFETs; requires external RC filter if externally sourced. |
| 10–13 C2H/C1H/C1L/C2L | Charge Pump Capacitor Terminals | Connect external 0.1 μF ceramic bucket capacitors (C1L–C1H, C2L–C2H) to generate VCRES. |
| 20 LGND | Logic Ground | Reference for VDD and logic inputs; must be connected to system ground, separate from PGND near IC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Charge Pump | Eliminates need for external high-voltage bias supply; enables full gate drive for high-side MOSFETs with only VDD and VM rails. |
| Shoot-Through Protection | Hardware-level prevention of simultaneous high-side/low-side FET conduction, avoiding destructive shoot-through current. |
| Independent Dual H-Bridge Control | Each bridge controlled by dedicated logic inputs (IN1A/IN1B, IN2A/IN2B), enabling asynchronous operation of two motors or one bipolar stepper. |
| Low Quiescent Current | IQVDD ≤ 1.0 mA (no signal); extends battery life in always-on portable devices such as digital cameras. |
| Fast Switching Times | tPLH/tPHL ≤ 0.5 μs (8 Ω load); supports high-frequency PWM without significant dead-time distortion. |

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 output current (1.2 A DC), lower RDS(on) (0.56 Ω typ), but requires external charge pump or higher VDD for full VM > 5 V operation. | Preferred for higher-torque motors; lacks integrated charge pump, increasing BOM count and layout complexity. | Select TB6612FNG when peak current > 0.7 A is required and board space allows external capacitor routing. |
| DRV8833 | Lower RDS(on) (0.3 Ω typ), 1.5 A peak, but no integrated charge pump and narrower VM range (2.7–10.8 V) with no undervoltage lockout. | Suitable for cost-sensitive designs where VM ≥ 4.5 V and external UVLO is acceptable. | Choose DRV8833 only if system includes external brownout detection and VM remains ≥ 4.5 V during operation. |
Compared with TB6612FNG and DRV8833, the MPC17529EV provides integrated charge pump and undervoltage shutdown in a compact VMFP package-ideal for space-constrained, battery-powered applications where reliability and minimal external components are critical.

FAQ
What is the maximum continuous output current per channel for the MPC17529EV?
The MPC17529EV supports 0.7 A DC continuous output current per H-bridge channel at TA = 25 °C, with peak current capability of 1.4 A for short durations (10 ms pulse, 200 ms interval). This rating assumes proper PCB thermal design with the exposed pad soldered to a copper pour to maintain junction temperature within limits.
Does the MPC17529EV require external charge pump capacitors?
Yes, the MPC17529EV requires two external 0.1 μF ceramic capacitors: one between C1L and C1H, and another between C2L and C2H. These form the "bucket" capacitors for the internal charge pump that generates VCRES (~13 V) for high-side gate drive. Omitting them disables high-side FET operation and causes driver failure.
What happens when the VDD supply drops below the undervoltage threshold on the MPC17529EV?
When VDD falls below the detection threshold (1.5–2.5 V), the MPC17529EV automatically places all four outputs (OUT1A/OUT1B/OUT2A/OUT2B) into high-impedance (tri-state) mode to prevent erratic motor behavior or logic corruption. Normal operation resumes once VDD rises above the threshold and input states are stable.
Can the MPC17529EV drive a bipolar stepper motor?
Yes, the MPC17529EV can drive a bipolar stepper motor by connecting one winding across OUT1A/OUT1B and the other across OUT2A/OUT2B. Its four operating modes (forward, reverse, brake, tri-state) and independent channel control enable full-step, half-step, or microstepping when paired with an external controller generating appropriate phase sequencing.
Is the MPC17529EV pin-compatible with the MPC17529EJ variant?
No, the MPC17529EV (20-pin VMFP) and MPC17529EJ (20-pin TSSOP with exposed pad) share identical pin functions and electrical specifications but differ in physical package dimensions, thermal performance, and land pattern. They are not mechanically interchangeable without PCB redesign, though schematic-level substitution is possible with layout adjustments.
