MPC17511AEVEL Übersicht
An H-bridge driver (also called a full-bridge driver) is a four-switch topology that can drive a load in both polarities from a single supply. H-bridges sit beneath stepper motor drivers, DC motor drivers, and motor-driver PMICs in the broader power management IC hierarchy. The MPC17511AEVEL integrates the four switches, gate drivers, control logic, and protection into one IC, eliminating the discrete MOSFET complexity that older designs required.
Key features include 1 A peak output current, low on-resistance DMOS output stages, parallel CMOS logic interface inputs (IN1, IN2, enable), shoot-through protection, undervoltage lockout, thermal shutdown, and a logic supply range compatible with 3.3 V and 5 V microcontrollers. The exposed pad (VMFP) lowers thermal resistance, allowing sustained 1 A operation without an external heatsink on moderately sized PCB copper pours.
The device uses an advanced BiC/DMOS process that combines CMOS control with DMOS power devices on one die. The architecture delivers fast switching (typical 200 ns propagation), low quiescent current, and integrated protection that would otherwise require external comparators and FETs. According to NXP datasheet MC17511, the device targets portable battery-powered designs where board space and efficiency are critical.
Typical applications include DSLR camera autofocus and zoom motors, portable printer paper-feed steppers, lens iris control, small valve and pump drivers, robotic actuators, and consumer toys. Battery-powered tools and medical pumps also use this topology.
When designing with this part, keep the high-current traces short and wide, tie the exposed pad to a solid ground pour, and place the 100 nF VMM bypass capacitor within 3 mm of the supply pin. For bipolar stepper operation, two MPC17511AEVEL devices are typically required (one per winding).

DSLR Camera Autofocus & Zoom Drive
The NXP MPC17511AEVEL drives small brushed DC motors in DSLR lens assemblies for autofocus (AF) and optical zoom (OZ) actuation. Its 1 A peak current, 0.45 ohm RDSon DMOS stages, and 2.7-5.7 V logic compatibility let it interface directly to image-processor GPIO while driving 3 V coreless motors. The exposed thermal pad allows compact board layouts under the lens barrel. Two MPC17511AEVEL devices handle AF and OZ independently, each providing full forward/reverse/brake control via IN1/IN2 logic. Compared to discrete bridges, the integrated shoot-through protection prevents lens-jam current spikes from damaging the driver, a critical reliability consideration.

Portable Printer Paper-Feed Stepper
The MPC17511AEVEL is used as the bipolar stepper driver per phase in portable thermal printers and label makers. With one IC per winding, full-step and half-step control are achieved via IN1/IN2 sequencing from a microcontroller. The 2 V to 6.8 V motor supply range covers 1S Li-ion (4.2 V) and 2S alkaline (3 V) battery packs. The 1 A current rating easily drives NEMA 8 or NEMA 11 size steppers used in handheld receipt printers. Integrated thermal shutdown protects the driver during paper-jam stall conditions, where motor winding current spikes. The CMOS logic interface simplifies connection to low-power MCUs without level shifters.
Empfohlen
Lens Iris Control
Professional and prosumer camera lenses use the MPC17511AEVEL to drive the iris actuator for aperture control. The driver's small 16-VMFP footprint and high integration allow it to fit within the iris ring housing. Four-quadrant operation (forward, reverse, brake, hi-Z) gives precise iris positioning. The DMOS output stage's low RDSon minimizes heat dissipation during continuous hold-current operation, important for video-recording scenarios where the iris holds position for extended periods. Logic-level compatibility with 3.3 V camera-bus microcontrollers simplifies PCB routing.
Empfohlen
Small Valve & Pump Drivers
Portable medical and laboratory instruments use the MPC17511AEVEL to drive miniature solenoid valves, peristaltic pumps, and diaphragm pumps. The 1 A peak current handles most small DC-motorized fluidics, and the wide 2-6.8 V motor supply range accommodates single Li-ion cell packs common in handheld medical devices. The exposed thermal pad provides efficient heat dissipation during continuous pump operation. The integrated undervoltage lockout prevents erratic valve actuation when battery voltage drops below the safe threshold.
Empfohlen
Robotic Actuators & Consumer Toys
Small hobby robots, RC servos, and educational consumer toys use the MPC17511AEVEL for brushed DC motor control. Its low component count and CMOS logic interface make it attractive for cost-sensitive designs. With 1 A capability, the driver easily powers micro metal gearmotors and N20-size motors used in robotics kits. The integrated protection features (thermal shutdown, shoot-through prevention, UVLO) prevent field failures in toys subject to stall currents and battery abuse.
Empfohlen
Battery-Powered Portable Tools
Cordless screwdrivers, small vacuum motors, and handheld fans use the MPC17511AEVEL for variable-speed brushed DC motor control. PWM applied to the EN or IN pins regulates speed with full torque at low RPM. The driver's 2.7-5.7 V logic range simplifies connection to battery-management ICs that produce 3.3 V system rails. The exposed thermal pad helps sustain high-current tool operation without external heatsinking, reducing assembly cost.

Wichtigste Unterscheidungsmerkmale
- Higher peak current in same 16-VMFP package (vs. MPC17510ATEP)
- Fully integrated protection features (vs. Discrete MOSFET H-bridge)
- Wide dual-rail supply range (vs. TB6612FNG (Toshiba))
Designhinweise
The 16-VMFP package provides an exposed thermal pad (EP) that MUST be soldered to a ground copper pour of at least 100 mm^2 to achieve rated 1 A continuous current. Without the EP connection, thermal resistance rises dramatically and the internal thermal shutdown will trigger during normal operation. Use thermal vias beneath the EP to bring heat to inner PCB layers.
Keep the high-current motor traces (VMM, OUT1, OUT2) short and wide - at least 0.5 mm per ampere of expected current. Place the VMM bypass capacitor (10 uF ceramic + 100 nF) within 3 mm of the VMM pin to suppress voltage ringing during PWM switching. Separate logic traces from power traces to prevent ground bounce from coupling into IN1/IN2/EN lines.
Do not exceed 6.8 V on VMM or 5.7 V on VCC - the DMOS transistors have limited avalanche energy and will fail. Always sequence VCC before VMM at power-up; reverse sequencing can cause logic latch-up. For bipolar stepper applications, ensure software dead-time between IN1/IN2 transitions to avoid shoot-through currents that exceed the 1 A rating.
