DRV110APWR Visão geral
What is a solenoid driver IC? A solenoid driver is a specialized power-management IC that switches an inductive load (a solenoid coil, relay, or valve) while controlling the current waveform. It sits hierarchically under motor / motion / ignition drivers, then power-management ICs, then analog semiconductors. By replacing discrete MOSFET+op-amp+comparator circuits with a single integrated controller, a solenoid driver saves PCB area, simplifies firmware, and enables accurate closed-loop current regulation for repeatable mechanical actuation.
Key features include a programmable peak-and-hold current profile (with separate peak and hold current set-points), internal PWM generation at a fixed switching frequency, an adjustable dither function for vibration reduction, and integrated thermal shutdown. The device supports 120V/230V AC and 6V-48V DC supply rails when used with appropriate external rectification, making it compatible with industrial control systems as well as 12V/24V automotive loads.
Architecturally, the DRV110APWR uses an internal charge-pump to drive an external N-channel MOSFET in low-side configuration, a sense resistor for current feedback, and a digital state machine that autonomously sequences the peak-then-hold profile. The internal 6V to 28V LDO powers the logic, removing the need for an auxiliary rail. Compared to discrete bang-bang drivers, the DRV110's PWM regulation eliminates the inrush current spike that erodes contact life and causes EMI.
Typical applications include HVAC damper valves, automatic door locks, vending-machine dispensing solenoids, industrial latching relays, automotive transmission shift solenoids, and printer hammer actuators. Anywhere a coil is energized repeatedly, the DRV110's hold-current mode reduces heating and extends coil lifetime.
When designing, ensure the sense resistor is sized for the desired peak current (VREF / Rsense), the external MOSFET's VDS rating exceeds the supply, and a flyback or TVS clamp is added across the coil. The PW package dissipates up to 1.5W; copper-pour heatsinking is recommended above 0.5W continuous dissipation.

Aplicações típicas
DRV110APWR é adequado para 7 aplicaçãos: HVAC Damper Valve Actuators, Automotive Door Lock Solenoids, Industrial Latching Relays, Vending Machine Dispensing Solenoids, Printer Hammer / Solenoid Actuators, Medical Infusion Pump Valves, Smart Lock / Access Control Bolts.
HVAC Damper Valve Actuators
The DRV110APWR drives 24V HVAC damper valves that must hold position against spring return force. Its peak-and-hold profile delivers a high pull-in current to seat the valve, then drops to a regulated 25-50% hold current that maintains position while dissipating under 0.5W per channel. Unlike a discrete MOSFET+op-amp solution, the DRV110's integrated charge-pump gate driver eliminates external bootstrap components, reducing BOM count by roughly 40%. The 14-pin TSSOP footprint drops directly onto existing HVAC control boards and the -40C to +125C operating range handles rooftop and plant-floor environments without derating.
Recomendado
Automotive Door Lock Solenoids
The DRV110APWR is well-suited for automotive door-lock and latch solenoids driven from a 12V battery. Its 6V-28V input range handles load-dump transients up to 28V, and the integrated thermal shutdown protects against stalled actuators. By replacing direct-drive circuits with peak-and-hold PWM regulation, the DRV110 reduces average coil current by 80-90% after pull-in, cutting key-off quiescent drain and extending battery life. The 14-pin TSSOP package fits behind door modules where board area is constrained, and its automotive-grade operating temperature range supports under-hood and door-jamb mounting.
Recomendado
Industrial Latching Relays
The DRV110APWR provides controlled current to industrial latching relays used in smart-grid and substation automation. Its adjustable peak-and-hold profile ensures the relay contacts seat fully with a strong initial pulse, then hold with minimal holding current to reduce coil heating during long energised periods. The 120V/230V AC mains capability (when rectified externally) matches utility-panel supplies, and the 0.33A continuous rating covers most control-relay coils. The 14-pin TSSOP and integrated thermal shutdown allow dense relay-driver cards without external heatsinks.
Recomendado
Vending Machine Dispensing Solenoids
Vending machines use 12V or 24V solenoids to dispense products, and the DRV110APWR's programmable peak-and-hold current extends solenoid life through millions of cycles. The integrated dither function applies a small AC modulation to the hold current, breaking static friction in the actuator mechanism and improving dispense reliability in humid environments. The 14-pin TSSOP sits alongside the vending machine's main controller, replacing 5-7 discrete components and saving roughly 80 mm² of board area. The IC's 6V-28V range accepts unregulated 12V/24V wall adapters without extra regulation.
Recomendado
Printer Hammer / Solenoid Actuators
The DRV110APWR drives impact-printer hammer solenoids and industrial marking actuators where repeatable, controlled pulses are required. Its peak-current setting (via Rsense) limits inrush to protect the coil insulation, while the PWM hold mode keeps the actuator seated between strokes without overheating. The integrated charge-pump drives a wide range of N-channel MOSFETs, supporting low-RDS(on) parts that keep dissipation under 0.5W at 24V. The TSSOP-14 footprint is compatible with existing printer-driver cards, enabling retrofit designs without board rework.
Recomendado
Medical Infusion Pump Valves
The DRV110APWR controls pinch-valve solenoids in medical infusion pumps where precise current regulation ensures repeatable flow rates. Its peak-and-hold profile delivers a defined pull-in current, then drops to a regulated hold current that the MCU can verify via onboard current sensing. The integrated thermal shutdown and -40C to +125C operating range meet IEC 60601-1 environmental expectations for medical equipment, and the 14-pin TSSOP package fits within the confined pump-housing PCBs. According to TI's DRV110 datasheet, the device's low quiescent current also extends battery life in portable infusion devices.
Recomendado
Smart Lock / Access Control Bolts
The DRV110APWR drives dead-bolt and latch solenoids in electronic smart-lock systems. Its 6V-28V input range accepts the common 12V supply used in access-control panels, and the peak-and-hold profile delivers a forceful pull-in to overcome spring preload, then drops to a low hold current to keep the bolt seated without overheating. The integrated charge-pump gate driver and TSSOP-14 footprint simplify PCB design in compact smart-lock modules. Designers can use the DRV110's dither feature to keep the bolt from seizing due to humidity in outdoor installations.

Notas de projeto
Estimated: at VIN=24V, IOUT=0.33A continuous into a coil, and assuming 1W internal dissipation in the DRV110APWR, the junction temperature rise above ambient is roughly 1W x theta_JA. Use at least 100 mm² of 1-oz copper pour tied to the exposed pad to keep junction rise under 50 C/W. Above 0.5W continuous, add a copper heatsink or forced airflow.
Place the external sense resistor (Rsense) within 5 mm of the SENSE pin to avoid ground-loop errors. Use a 1% tolerance resistor rated for at least 2x the peak current, and pair it with a 100 nF X7R bypass cap on the SENSE node. The exposed thermal pad (pin 14) MUST be soldered to a copper area of at least 50 mm² for thermal relief, otherwise the device will enter thermal shutdown prematurely.
Do not omit the external flyback diode or TVS clamp across the inductive load - even with the DRV110's internal gate driver, the absence of a free-wheeling path will generate >100V spikes that destroy the MOSFET. Keep the gate-drive trace to the external MOSFET shorter than 25 mm to prevent ringing, and add a 10 ohm gate resistor if the trace exceeds 10 mm.
Route the high-current OUT1/OUT2 traces away from the analog SENSE and PROG pins to avoid capacitive coupling. According to TI's DRV110 application notes, a ground pour under the analog section with a single connection to the power ground near the sense resistor improves current-sensing accuracy. The internal LDO requires a 1 uF X7R bypass on VCC (pin 5) placed within 3 mm of the pin.
