Product details
Overview
MPC17533EVEL from Freescale Semiconductor is a monolithic dual H-bridge motor driver IC designed for portable electronics, supporting bipolar stepper and brushed DC motors with 0.7 A continuous/1.4 A peak output current, 2.0–6.8 V motor supply range, and 1.2 Ω max RDS(ON) at 25 °C; used in camera lens actuators and optical disk drive head positioners.
For engineers reviewing the MPC17533EVEL datasheet, MPC17533EVEL pinout, MPC17533EVEL application, or MPC17533EVEL equivalent, key selection criteria include dual-channel independent control via parallel MCU interface, shoot-through protection, undervoltage shutdown, PWM operation up to 200 kHz, and 16-pin VMFP package thermal performance.
Technical Context
The MPC17533EVEL integrates two fully independent H-bridge power stages with CMOS-compatible 3.0 V/5.0 V logic inputs and a dedicated OE (low-true) enable pin. Each bridge supports forward, reverse, brake, and high-impedance tri-state modes via IN1A/IN1B and IN2A/IN2B control pairs.
It employs internal gate drivers with external VG bias input (up to 14 V) to ensure full enhancement of high-side MOSFETs when VM exceeds VDD-critical for efficient operation in low-VDD, high-VM configurations like 3.0 V logic / 5.0 V motor supply systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 0.7 A DC / 1.4 A peak per channel - supports sustained micromotor loads and transient torque demands. |
| RDS(ON) | 1.2 Ω max (source + sink, 25 °C) - minimizes conduction loss and self-heating at rated load. |
| Supply Range | VM = 2.0–6.8 V; VDD = 2.7–5.7 V - enables direct battery operation (e.g., single Li-ion or 2×AA) with logic-level compatibility. |
| PWM Frequency | Up to 200 kHz - allows high-resolution speed/torque control with minimal audible noise and low switching loss. |
| Protection Features | Integrated shoot-through prevention + undervoltage shutdown (VDDDET = 1.5–2.5 V) - prevents latch-up and unsafe operation during brownout. |
| Logic Interface | 3.0 V/5.0 V CMOS-compatible inputs - eliminates level-shifting circuitry for most microcontrollers. |
Pinout & Package
Package: 16-pin Very Thin Mini Flat Package (VMFP), Pb-free, 3.0 mm × 3.0 mm × 0.55 mm body, exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1A, OUT1B, OUT2A, OUT2B | H-Bridge Output Terminals | Four high-current outputs forming two independent full bridges; each pair drives one motor winding or one DC motor. |
| VM1, VM2 | Motor Power Supply Inputs | Separate pins for motor supply connection; must be tied together externally to minimize voltage drop and improve current sharing. |
| VDD, LGND | Logic Supply & Ground | Provides power and reference for internal logic; includes undervoltage detection circuitry tied to VDD. |
| OE | Output Enable (Active-Low) | Global disable: pulls all four outputs to high-impedance regardless of INx states - enables safe power sequencing and fault isolation. |
| IN1A, IN1B, IN2A, IN2B | Bridge Control Inputs | Direct parallel logic interface; truth table defines forward/reverse/brake/tri-state behavior per bridge without external decoding. |
| VG | Gate Driver Bias Input | External 12–13.5 V supply for high-side MOSFET gate drive - required to maintain low RDS(ON) when VM > VDD. |
| PGND1, PGND2 | Power Ground Returns | Dedicated high-current ground paths for each H-bridge; must be connected to common PCB ground plane with low-inductance routing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Independent H-Bridges | Enables simultaneous control of two brushed DC motors or precise commutation of one bipolar stepper motor without external logic. |
| Low RDS(ON) (0.8 Ω typ) | Reduces I²R losses and thermal rise at 0.7 A, allowing compact PCB layout and extended battery life in portable devices. |
| Shoot-Through Protection | Hardware-level prevention of cross-conduction between high- and low-side MOSFETs within each bridge - eliminates risk of destructive shoot-through current. |
| Undervoltage Shutdown | Automatically disables outputs when VDD drops below 1.5–2.5 V threshold - prevents erratic behavior and MOSFET partial turn-on during power ramp-down. |
| 200 kHz PWM Capability | Supports high-frequency modulation for smooth motor control, reduced acoustic noise, and improved current regulation accuracy. |

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; integrated VREF for current limiting; no external VG pin required. | Preferred for higher-current brushed DC motors; lacks separate VM1/VM2 pins and uses single VM supply. | Select TB6612FNG when needing higher current headroom and simplified biasing, but verify PCB layout compatibility with shared VM and absence of dual VM routing. |
| DRV8833 | Lower 1.5 A peak current; built-in charge pump eliminates need for external VG; smaller 16-pin QFN package. | Better suited for space-constrained designs where gate drive simplicity outweighs maximum efficiency at high VM/VDD differentials. | Choose DRV8833 for ultra-compact layouts and lower BOM count, accepting slightly higher RDS(ON) (1.7 Ω typical) versus MPC17533EVEL's 0.8 Ω typical. |
Compared with TB6612FNG and DRV8833, the MPC17533EVEL offers superior thermal efficiency at 0.7 A due to its lower RDS(ON), explicit dual VM routing for balanced power delivery, and external VG control for optimal high-side drive under wide VM/VDD ratios - making it ideal for precision portable motor systems where voltage margin and loss budget are critical.

FAQ
What is the maximum motor supply voltage supported by the MPC17533EVEL?
The MPC17533EVEL supports a motor supply voltage (VM) range of 2.0 V to 6.8 V, with absolute maximum rating of 8.0 V. Operation beyond 6.8 V is not recommended for reliable long-term performance, as specified in the Electrical Characteristics table. The MPC17533EVEL is optimized for battery-powered portable applications such as cameras and disk drives where VM typically ranges from 3.0 V to 5.0 V.
Does the MPC17533EVEL require an external gate drive voltage, and why?
Yes, the MPC17533EVEL requires an external gate drive voltage applied to the VG pin (12–13.5 V typical). This is necessary to fully enhance the high-side MOSFETs when the motor supply VM exceeds the logic supply VDD - for example, in 3.0 V MCU / 5.0 V motor configurations. Without proper VG bias, RDS(ON) increases significantly, reducing efficiency and increasing thermal stress on the MPC17533EVEL.
How does the undervoltage shutdown function work in the MPC17533EVEL?
The MPC17533EVEL monitors VDD and triggers undervoltage shutdown when the supply drops below 1.5–2.5 V (typical threshold). Upon detection, all H-bridge outputs transition to high-impedance tri-state mode within 10 ms, preventing unpredictable switching and potential shoot-through. When VDD recovers above the threshold, the MPC17533EVEL automatically resumes operation based on the current state of INx and OE pins - no reset pulse is required.
Can the MPC17533EVEL drive a bipolar stepper motor, and how is it configured?
Yes, the MPC17533EVEL is explicitly designed to drive bipolar stepper motors by configuring its two independent H-bridges as phase A (OUT1A/OUT1B) and phase B (OUT2A/OUT2B). The truth table defines full-step and half-step sequences via IN1A/IN1B and IN2A/IN2B logic combinations. Brake and tri-state modes allow precise current decay control, essential for microstepping stability and vibration reduction in the MPC17533EVEL application.
What thermal considerations apply to the MPC17533EVEL in a 16-pin VMFP package?
The MPC17533EVEL in its 16-pin VMFP package has a junction-to-ambient thermal resistance (RθJA) of 150 °C/W when mounted on a 37 mm × 50 mm × 1.6 mm glass epoxy board. To maintain safe operation at 0.7 A continuous load, designers must use wide copper traces, connect the exposed thermal pad to a solid ground plane, and place ≥10 μF low-ESR bulk capacitance near VM and VDD pins. Derating is required above 65 °C ambient per the datasheet's temperature range specification.
