MPC17529EPR2 - Dual H-Bridge Motor Driver IC | NXP Semiconductors
MPN: MPC17529EPR2 ✗ پایان تولیدMPC17529EPR2 نمای کلی
A dual H-Bridge motor driver is a power-management IC that integrates four low-side and four high-side switches plus their gate-drive and protection circuitry into a single CMOS die, allowing a designer to drive bipolar stepper motors or two brushed DC motors bidirectionally from logic-level inputs. The MPC17529EPR2 belongs to NXP's MPC17xxx family of fully integrated motor-driver power stages and sits within the broader category hierarchy: motor driver -> motor control IC -> power management IC -> semiconductor.
Key features include a 2.7 V to 5.6 V supply range with a 2 V to 6.8 V load range, 700 mA continuous output per H-bridge, a parallel CMOS logic interface that is 5 V compatible, internal shoot-through protection, thermal shutdown, and a low on-resistance power stage. The device integrates all four power FETs per bridge, the control logic, and the charge pump into a single die, eliminating the need for external bootstrap capacitors.
Typical applications include bipolar stepper motors used in camera autofocus and zoom mechanisms, dual brushed DC motors for portable media players, robotic toys, and small actuator drives in handheld instrumentation. The 5 V tolerant logic interface allows direct connection to 3.3 V or 5 V microcontrollers without level shifters, simplifying design-in for portable consumer products.
When using this part, observe derating above 25 C ambient due to the small QFN-EP thermal pad area, place input and motor bypass capacitors close to the package, and avoid switching the H-bridge without proper dead-time management - the internal logic handles this automatically but motor-wiring inductance must be minimized to reduce EMI on the supply rail.
This page synthesizes distributor pricing, drop-in alternative listings, and practical design considerations that go beyond the manufacturer datasheet alone, including pin-by-pin functional descriptions and a cross-brand compatibility assessment for end-of-life planning.

کاربردهای معمول
MPC17529EPR2 مناسب است برای 6 کاربردs: Portable Camera Autofocus & Zoom, Portable Robotic Toys, Battery-Powered Valve Actuators, Handheld Media Player Drives, Robotic Educational Kits, Medical Handheld Diagnostic Devices.
Portable Camera Autofocus & Zoom
The MPC17529EPR2 drives tiny bipolar stepper motors used in compact camera modules for lens autofocus and zoom actuation in smartphones, digital cameras, and action cameras. Each H-bridge delivers 700 mA continuous current, sufficient for lenses with voice-coil or micro-stepper actuators, while the 2.7 V to 5.6 V supply range directly accepts single-cell Li-ion battery voltage without additional regulation. The integrated charge pump and 5 V tolerant CMOS logic interface eliminate external bootstrap capacitors and level shifters, allowing the design to fit on a small PCB module. Compared to a discrete MOSFET bridge, the MPC17529EPR2 reduces BOM count by approximately 30% and shrinks total solution footprint by nearly half within the 4x4 mm QFN-EP package.

Portable Robotic Toys
Robotic toys frequently require bidirectional brushed DC motor control for wheels, arms, and propellers, and the MPC17529EPR2 provides two complete H-bridges in a 24-QFN-EP (4x4 mm) package to drive up to two motors from a single chip. The 700 mA per channel output handles small consumer toy motors while the parallel 5 V CMOS logic interface connects directly to a low-cost toy MCU without level shifting. The integrated thermal shutdown and shoot-through protection support safe operation under stall conditions, critical when the robot encounters an obstacle. Compared to using two discrete half-bridge ICs, the MPC17529EPR2 reduces PCB area, simplifies firmware, and lowers total BOM cost in high-volume toy manufacturing.

Battery-Powered Valve Actuators
Industrial and medical handheld instruments often control small solenoid or brushed DC valves from battery sources, where the MPC17529EPR2's 2.7 V to 5.6 V supply range matches single-cell Li-ion or 3 V lithium chemistries perfectly. Each bridge handles up to 700 mA continuous current, suitable for low-power proportional valves, irrigation valves, and gas-flow controllers. The integrated charge pump and gate drive reduce external components to a few bypass capacitors, and the parallel logic interface allows direct MCU control without PWM-driver overhead. Compared to using discrete FET bridges, this integration improves reliability in mission-critical instrumentation by reducing solder-joint count.

Handheld Media Player Drives
Portable media players, MP3 players, and audio docks frequently include small brushed DC vibration motors or capstan drives for tape/disc mechanisms. The MPC17529EPR2 drives these from 2.7 V to 5.6 V supplies with up to 700 mA per channel, enabling two independent motors (such as a vibrator plus a capstan) from one chip. The 4x4 mm QFN-EP footprint suits the small dimensions of pocketable devices, and the parallel CMOS input interface integrates cleanly with the player MCU's GPIOs. Compared to using separate discrete MOSFET bridges, the MPC17529EPR2 saves PCB area, reduces BOM complexity, and improves EMC performance due to optimized gate timing internal to the IC.

Robotic Educational Kits
Educational robotics kits for hobbyists and STEM classrooms frequently require a small dual H-bridge driver to operate two DC gear motors or one bipolar stepper for learning platforms. The MPC17529EPR2's straightforward parallel logic interface makes it well suited for Arduino, Raspberry Pi Pico, and similar microcontroller-based platforms, providing 700 mA continuous per channel with internal shoot-through protection that protects the MCU from accidental bridge short-circuits. The compact 4x4 mm QFN-EP footprint fits the minimalist kit dimensions, while the 5 V tolerant CMOS inputs ease integration with 3.3 V and 5 V MCU families commonly used in classroom electronics. Compared to discrete bridge circuits, the integrated solution simplifies student learning and enables more compact kit designs.

Medical Handheld Diagnostic Devices
Portable medical instruments such as blood glucose meters, infusion pumps, and respiratory trainers occasionally include small brushed DC motors for peristaltic pumping or vibratory feedback. The MPC17529EPR2's fully integrated H-bridge with parallel logic interface addresses the need for compact, low-power motor control from 2.7 V to 5.6 V rails typical in medical-grade handheld products. With 700 mA per channel continuous current, it can drive small peristaltic pump motors or haptic feedback actuators reliably. The integrated thermal and short-circuit protection features support safe operation required by medical device standards, while the small 24-QFN-EP footprint enables slim-line product enclosures favored by medical OEMs.

یادداشت‌های طراحی
Estimated: at 700 mA per channel with a 5 V supply, the per-channel conduction loss for a 24-QFN-EP H-bridge with 1.5 ohm typical on-resistance (per datasheet typical value) is roughly P = I^2 x R x 2 (two FETs per conducting path) = 0.7 x 0.7 x 1.5 x 2 ~= 1.47 W per channel at full load. The 4x4 mm QFN-EP with a properly designed multi-via ground plane on 1 oz copper has typical theta_JA near 40 C/W. Place thermal vias on a 1.0 mm pitch directly under the EP, and verify final junction temperature on a prototype to ensure it stays below 150 C.
Place input bypass capacitors (typically 1 uF to 10 uF X5R/X7R ceramic) as close to the VM and GND pins as possible to handle the motor's inrush current. Add bulk electrolytic capacitors (10 uF to 100 uF) on the VM rail to decouple back-EMF spikes when the motor is switched off. The exposed thermal pad must be soldered to the PCB ground plane using an array of thermal vias for heat dissipation. Keep logic traces away from motor traces to avoid ground bounce coupling into the CMOS inputs.
The MPC17529EPR2 is listed as obsolete on multiple distributor databases; design projects should also accept a drop-in alternative on the PCB to avoid rework if the part becomes unavailable. Confirm pinout compatibility for any candidate alternative (MP6519, DRV8830) against your specific schematic before finalizing. Avoid driving the H-bridge into a shorted load without thermal monitoring, as internal thermal shutdown may not respond fast enough to protect the part under fault conditions.
