MPC17529EVEL - 0.7A Dual H-Bridge Motor Driver | NXP Semiconductors
MPN: MPC17529EVEL ✓ Hoạt độngMPC17529EVEL Tóm tắt
An H-Bridge motor driver is a power-IC topology that uses four switches (two high-side and two low-side MOSFETs/ transistors) arranged in an 'H' configuration to drive a DC or bipolar stepper motor winding bidirectionally from a single supply rail. The dual-H topology puts two complete bridges on one die, enabling simultaneous control of two brushed DC motors, one bipolar stepper, or a single higher-current motor with paralleled outputs. Within the broader taxonomy, H-bridge drivers belong to motor drivers, which sit under motor/motion control ICs, which are a subfamily of power management ICs (PMIC).
Key features of the MPC17529EVEL include 0.7 A continuous DC output per bridge, low RDS(on) DMOS output stages with built-in shoot-through (cross-conduction) protection, an internal charge pump that eliminates the need for an external bootstrap capacitor on the high-side FETs, parallel 3.0 V / 5.0 V CMOS logic inputs, and an undervoltage lockout that disables the outputs when VCC drops below the operating threshold. The control logic uses simple parallel INx/ENx inputs rather than PWM/PWM logic, simplifying firmware for cost-sensitive designs.
Typical applications include bipolar stepper motor drivers for camera lens positioners and disk-drive head actuators, brushed DC motor drivers in portable equipment such as toys, robotics, small appliances, and disk drives, and battery-powered mechanisms needing two-axis motion. The wide 2.0 V to 6.8 V supply range makes it directly compatible with single-cell Li-ion (3.0-4.2 V), two-cell alkaline (2.0-3.2 V), and 5 V regulated rails.
When designing with this part, place a 0.1 uF ceramic bypass capacitor as close as possible to the VM and VCC pins to suppress charge-pump switching noise. The exposed pad of the VMFP package must be soldered to a sufficient copper pour to keep junction temperature within the -30 C to +85 C operating range at 0.7 A continuous current.

Ứng dụng tiêu biểu
MPC17529EVEL phù hợp cho 6 Áp dụngs: Camera Lens Positioner (Bipolar Stepper), Disk Drive Head Positioner, Portable Robotic Toy (Brushed DC Motors), Battery-Powered Locking Mechanism, Small Appliance Vane / Fan Driver, Medical Pipette / Syringe Drive.
Camera Lens Positioner (Bipolar Stepper)
The MPC17529EVEL drives one bipolar stepper motor (two windings, four wires) in compact camera lens positioners. Its two on-chip H-bridges handle the bidirectional current reversal required to step the motor: each winding is driven by one bridge, and CMOS parallel inputs set the direction and step rate. At 3 V to 5 V from a single Li-ion cell or a 5 V rail, the 0.7 A per-bridge rating covers typical micro-stepper mechanisms used in mobile cameras and miniature autofocus assemblies. The internal charge pump removes the need for bulky bootstrap capacitors, allowing 6 mm x 6 mm PCB implementations.

Disk Drive Head Positioner
In 2.5-inch and small-form-factor disk drives, the MPC17529EVEL drives the bipolar stepper that moves the read/write head across the platter. The 0.7 A continuous rating per bridge provides enough current for sub-50 mm-diameter platters, while the 3.0 V / 5.0 V CMOS parallel logic lets a small microcontroller command the head position without complex PWM generation. Undervoltage lockout protects the media by parking the head cleanly when VM collapses, and shoot-through protection prevents the back-EMF transients common to moving-mass mechanisms from destroying the output FETs. Operating temperature -30 C to +85 C covers most drive operating environments.

Portable Robotic Toy (Brushed DC Motors)
The MPC17529EVEL drives two brushed DC motors (one per bridge) in portable robotic toys powered by two AA cells or a single Li-ion cell. Each bridge delivers up to 0.7 A continuous at 3 V to 5 V, which is well-matched to small gearmotors that draw 200-600 mA under typical load. The exposed-pad 20-VMFP package dissipates the 2 W of full-load power over a small copper pour. Parallel INx/ENx inputs give the host MCU direct start/stop and direction control using two GPIO pins per motor, eliminating the firmware overhead of PWM-complementary timing required by older FET-driver designs.

Battery-Powered Locking Mechanism
The MPC17529EVEL drives the brushed DC motor in battery-operated cable locks, latch actuators, and smart-lock bolts. Two bridges allow simultaneous control of one drive motor and one over-ride motor (or two axis latches) from a 3 V Li-ion supply. Its 2.0 V minimum VM rating permits operation down to critical low-battery conditions during unlock events, and the <2 uA logic quiescent current lets the device stay in standby while idle. The integrated undervoltage lockout prevents the lock from stalling mid-cycle when the cell voltage sags under load, which would otherwise be a lockout-failure mode in discrete designs.

Small Appliance Vane / Fan Driver
The MPC17529EVEL drives two small DC fans or oscillatory vanes in small appliances such as air purifiers, handheld vacuums, and personal cooling fans. With 0.7 A per bridge and 2.0 V to 6.8 V VM, a single 3.7 V Li-ion battery pack can drive both fans simultaneously. The shoot-through protection prevents the back-EMF spikes from fan coast-down events from destroying the outputs, and the integrated charge pump means there is no need for an external bootstrap network in the compact fan housings typical of consumer appliances. Operating temperature -30 C to +85 C covers the warm-environment conditions inside appliance enclosures.

Medical Pipette / Syringe Drive
In portable medical pipettors, syringe pumps, and handheld dosing devices, the MPC17529EVEL drives a single brushed DC motor (paralleled outputs) or two small motors (independent bridges) from a Li-ion cell. The 0.7 A continuous rating per bridge, with parallel-mode doubling if both bridges feed one motor, supplies the 0.5 to 1 A typically needed by a precision syringe drive. The CMOS 3 V / 5 V compatible logic interface integrates directly with a low-power medical MCU without level shifters. Its internal charge pump and shoot-through protection reduce failure modes critical to medical-grade single-fault safety systems.

Ghi chú thiết kế
At 0.7 A continuous per bridge with VM = 5 V and one bridge active, the package dissipates approximately 1.4 W. Estimated: assuming 0.6 ohm total H-bridge RDS(on) at 25 C, the 20-VMFP exposed-pad package requires at least 1 square inch of 1 oz copper on top layer (or an internal thermal via array) to keep junction temperature rise below 25 C above ambient. If both bridges run continuously, total dissipation reaches 2.8 W and the copper area or thermal vias must roughly double. Failure to provide adequate thermal relief may trigger the internal thermal shutdown in tight enclosures.
Place a 0.1 uF X7R ceramic bypass capacitor as close as possible to the VM pin and a second on the VCC pin. Use short, wide motor traces (>= 1 oz copper, 50 mil minimum width for 0.7 A) and keep motor traces routed away from analog feedback lines. The exposed die pad of the 20-VMFP must be soldered to a continuous copper plane -- do not flood only signal traces under the pad. Reverse polarity on VM (negative applied first) is not protected; add a series Schottky diode or P-channel reverse-protection FET if reverse-battery conditions are possible.
Do not exceed the 6.8 V absolute maximum VM rating; many designers apply a 7.2 V Li-ion or a 6.9 V LDO output and trip the over-voltage clamp, which destroys the DMOS outputs. Do not parallel both bridges to a single motor unless the absolute max ratings of both bridges and the combined copper area are sized for 2x the continuous current -- the same pin limits apply per bridge. Always honor the ENx truth-table logic (refer to the datasheet); driving INx while EN is low will inhibit output but does not guarantee the bridge enters a low-power state.
The internal charge pump operates at a fixed frequency between 100 kHz and 500 kHz typical. Estimated: a high-EMI environment with a long motor cable may need an external 1 nF to 10 nF snubber across each motor terminal to suppress dV/dt ringing that can couple back into adjacent analog circuits. If the design includes a feedback ADC near the driver, place 100 ohm series resistors and 100 pF shunt caps on sensitive analog traces that pass within 5 mm of the bridge outputs.
