MPC17559EP - Quad H-Bridge Low-Voltage Motor Driver | NXP
MPN: MPC17559EP ✗ پایان تولیدMPC17559EP نمای کلی
A motor driver is a power-management IC that converts low-current logic signals from a microcontroller into the high-current phase voltages required by DC, stepper, or brushless DC (BLDC) motors. In the broader power-electronics taxonomy, the MPC17559EP sits within the motor-driver category, itself a subset of motion-control ICs under power management; it descends from the H-bridge topology that uses four switches to reverse current flow through a DC motor, enabling bidirectional rotation. The MPC17559 extends this topology with two parallel 3-phase outputs plus two H-bridges on a single die, which is unusual at this footprint size and supports extremely compact camera/lens or vibration-module designs.
Key features include 300 mA continuous output current per channel, integrated over-current and thermal protection, low quiescent current to preserve battery life, and a low on-resistance Power MOSFET output stage. The 56-QFN package achieves a thermal resistance (theta JA) suitable for natural-convection cooling on a 1 oz copper PCB land, while the exposed pad provides direct heat dissipation into the board.
The internal architecture uses four N-channel Power MOSFETs with common-drain outputs arranged as two configurable 3-phase bridges and two H-bridges. Logic inputs accept 1.8 V CMOS levels directly from modern microcontrollers, eliminating the need for level shifters. The chip targets portable applications where board area and standby current dominate design priorities.
Typical applications include camera lens autofocus drivers, vibrator and stepper motor control in mobile phones, BLDC cooling fans, two-phase stepper indexing, and dual-coil DC actuator driver stages. Designers favor the part when four motors must be driven concurrently from a single lithium-ion or USB-supplied rail.
When designing with the MPC17559EP, evaluate total worst-case dissipation against the package thermal envelope. At VIN=3.5 V driving four channels at 300 mA simultaneously, dissipation is non-trivial and requires generous copper thermal vias under the exposed pad; however, the part's wide logic compatibility usually eliminates external level-shifters and reduces overall BOM cost.
This page consolidates distributor pricing, same-package drop-in alternatives, and practical PCB thermal notes not offered by the manufacturer datasheet, helping engineers evaluate MPC17559EP for next-generation portable designs.

کاربردهای معمول
MPC17559EP مناسب است برای 6 کاربردs: Camera Lens Autofocus Driver, Mobile Phone Vibrator Motor Driver, Portable BLDC Cooling Fan, Two-Phase Stepper Motor Indexer, Dual DC Actuator Controller, Portable Robotic Servo Driver Hub.
Camera Lens Autofocus Driver
The MPC17559EP's quad H-Bridge topology and 300 mA per-channel drive capacity make it ideal for camera lens autofocus and iris-actuator stages. Two of its H-bridges can be paralleled into one voice-coil autofocus (VCM) motor while a separate H-bridge drives an iris-shutter mechanism, all from a single 1.8-3.5 V Li-ion supply without external level shifters. The 56-QFN (8x8 mm) exposed-pad package fits beneath the actuator stack on typical 4 mm x 4 mm camera modules where PCB height is constrained. Designers value the part because it consolidates what was historically two or three discrete driver ICs into a single die.

Mobile Phone Vibrator Motor Driver
Mobile phone haptic feedback uses an eccentric rotating-mass (ERM) or linear resonant actuator (LRA) that requires a low-voltage H-bridge driver powered directly from the 1S Li-ion rail. The MPC17559EP's 1.8-3.5 V supply window matches this source and its 300 mA per-channel capability easily drives pulse-mode haptic patterns. Two independent vibrators can be supported simultaneously by separate H-bridge channels, or PWM modulation can be applied for variable-amplitude buzz on a single actuator. The exposed-pad QFN minimizes PCB area in slim-phone layouts.
پیشنهادی
Portable BLDC Cooling Fan
Low-voltage brushless DC cooling fans used in projectors, mini-PCs and battery powered electronics can be driven directly by the MPC17559EP's two configurable 3-phase bridges. The 300 mA per-channel rating suits fans up to roughly 2-3 W mechanical output, typical of small-diameter blower or sleeve-bearing fans in handheld equipment. Direct 1.8-3.5 V supply lets designers eliminate the boost converter normally required when interfacing 3.3 V logic to fans rated for higher voltages.
پیشنهادی
Two-Phase Stepper Motor Indexer
Stepper motors in camera zoom, vending mechanisms and printer heads can be driven by reconfiguring the MPC17559EP's bridges as a two-phase full-step or half-step indexer. Each motor coil receives up to 300 mA via a half-bridge pair, while the second H-bridge drives a second coil or a separate DC actuator. The 1.8 V logic-level inputs interface directly to a microcontroller without external gate drivers, reducing BOM and board space in stepper subsystems.
پیشنهادی
Dual DC Actuator Controller
The MPC17559EP provides two complete H-bridges for driving dual bidirectional DC loads such as solenoid valves, latches or relay coils. Each H-bridge handles up to 300 mA continuously with internal flyback handling from the MOSFET body diodes. In access-control hardware or printer paper-handling modules this topology reduces board complexity by replacing four discrete MOSFETs and a charge pump with a single QFN.
پیشنهادی
Portable Robotic Servo Driver Hub
Educational and hobby robotics boards use small RC servos that can be driven via the MPC17559EP acting as a 4-channel half-bridge/PWM controller, especially in low-voltage compact bots. While RC servos natively handle their own PWM decoding, the part is also useful for converting logic-level signals into half-H drive for brushed direct-drive miniature motors. The 56-QFN size supports small-form-factor robot joints that require multiple low-current channels.

یادداشت‌های طراحی
Estimated: at worst-case Vin=3.5 V driving four channels at 300 mA with simultaneous operation, total internal dissipation is on the order of 0.5-1.0 W assuming Power MOSFET Rds(on) of ~0.4 ohm per FET. The 56-QFN exposed-pad package must be soldered to a PCB thermal land with at least 1 oz copper and thermal via array (typically 6-9 vias under the pad) to keep junction temperature within safe limits. Without these layout practices the 8x8 mm footprint cannot reliably dissipate full-power operation.
Place the device ground pin connections to a single uninterrupted ground plane that ties the exposed pad directly to the PCB bottom copper. Decoupling on Vsup requires a 10 uF ceramic plus 0.1 uF high-frequency bypass capacitor close to the supply pin; the datasheet recommended bypass must be observed to prevent logic glitches on INx inputs that could propagate to OUTx outputs.
Do not tie logic inputs floating - all INx lines must be actively driven or pulled to a defined state. Back-EMF from inductive loads can exceed 3.5 V if the load is abruptly stopped; ensure motor coils include snubbing or rely on the part's internal clamp diodes. The MPC17559EP is NXP-end-of-life on some channels - design new layouts with verified stock from authorized distributors to avoid counterfeit risk on the second-hand market.
