LV8860V-TLM-H Présentation
A fan motor driver (also called a single-phase BLDC fan driver or single-phase full-wave driver) is a power-management IC that commutates a two-coil brushless DC motor by alternately switching two half-bridges in synchronization with the rotor position, typically detected via a back-EMF sensing network. Fan drivers sit hierarchically under motor drivers, which belong to the broader power management and motion control IC category. Compared to discrete MOSFET bridges driven by a microcontroller, integrated fan drivers reduce BOM count, PCB area, and acoustic noise while providing built-in protection features such as thermal shutdown, current limiting, and lock rotor detection.
Key features include Silent PWM drive for reduced audible switching noise, full-wave commutation for low torque ripple, lock detection with auto-restart, soft-start functionality, and integrated thermal shutdown. The 16-pin SSOP (LSSOP) package provides a compact footprint suitable for fan-embedded PCBs. The device accepts a wide supply range up to the 24 V fan bus and supports speed control via an external PWM signal, making it compatible with standard 4-wire PWM fan command interfaces used in PC, server, and industrial cooling subsystems.
The LV8860V uses a Bi-CMOS process that combines bipolar output drive strength for the power H-bridge with low-power CMOS logic for control. Full-wave commutation with Silent PWM minimizes switching losses and reduces the high-frequency acoustic content that fans couple into chassis. Built-in lock detection rotates the rotor through a forced-commutation pattern during a stall event and automatically restarts when rotation recovers, eliminating the need for an external supervisory timer.
Typical applications include CPU cooling fans, server and workstation blowers, industrial inverter fans, and 24 V office-automation equipment. The wide supply range and Silent PWM drive make it well suited for applications where acoustic noise and EMI compliance are critical design constraints.
When designing with this device, ensure adequate copper area under the exposed pad for thermal relief, follow the recommended input bulk capacitance to absorb the reactive return current, and verify that the lock-detection timing matches the rotor inertia of the specific fan you are pairing with this driver.

Applications typiques
LV8860V-TLM-H convient pour 6 applications: CPU and PC Cooling Fans, Server and Workstation Blowers, Industrial Inverter Cooling Fans, Office Automation Equipment, 24-V Industrial Fan Modules, Telecom and Network Switch Cooling.
CPU and PC Cooling Fans
The LV8860V-TLM-H's Silent PWM drive and integrated full-wave H-bridge make it a strong fit for 4-wire PWM CPU and case fans where acoustic noise is critical. Speed is commanded directly by the host PWM signal, while Silent PWM reduces the reactive current the fan couples into the 12 V rail, lowering switching losses and high-frequency acoustic content. Place a 10 uF input bulk capacitor and follow the SSOP-16 thermal copper recommendations. Pair this driver with a standard tach-output fan to deliver full PC-platform PWM speed control.
Recommandé
Server and Workstation Blowers
The LV8860V-TLM-H supports 24 V fan buses and integrates lock-rotor detection with auto-restart, which is essential for server blowers that must recover from a stalled rotor without host intervention. Silent PWM reduces EMI coupling into adjacent high-speed serial lanes, an important consideration in dense server chassis. The 16-SSOP footprint and wide supply tolerance simplify layout for hot-swap fan trays. Use this driver where you need industrial-grade reliability with automatic stall recovery.
Recommandé
Industrial Inverter Cooling Fans
In factory automation and motor-drive inverter enclosures, the LV8860V-TLM-H provides a compact 16-SSOP fan drive solution that tolerates the 24 V industrial bus and reduces reactive current with Silent PWM. Lock detection with auto-restart eliminates the need for an external supervisory timer, simplifying the BOM in remote panels where service access is limited. Pair this driver with industrial-grade fans whose rotor inertia matches the datasheet's lock-recovery timing for reliable restart after a stall.
Recommandé
Office Automation Equipment
Office-automation printers, copiers, and multifunction devices benefit from the LV8860V-TLM-H's Silent PWM architecture, which keeps acoustic emissions low enough for office environments. The wide supply range, including 24 V, fits the internal rails of mid-size MFP power architectures without extra regulators. Built-in thermal shutdown protects the driver if the cooling fan itself is obstructed, preventing printer shutdowns. Use this driver when acoustic comfort and reliable lock recovery are design priorities.
Recommandé
24-V Industrial Fan Modules
The LV8860V-TLM-H is explicitly designed for 24 V fan modules used in industrial cooling, making it a strong fit for cabinet ventilation, variable-frequency drive cooling, and telecom rack fans. Silent PWM reduces conducted EMI on the 24 V rail, easing compliance with industrial EMI standards. Lock detection with auto-restart is critical in unattended cabinets where a stalled fan must recover on its own. Use this driver in designs that demand silent operation, automatic stall recovery, and a compact 16-SSOP footprint.
Recommandé
Telecom and Network Switch Cooling
Network switches and telecom base stations depend on redundant variable-speed fans whose drivers must integrate cleanly with PWM-controlled fan headers. The LV8860V-TLM-H accepts a parallel PWM command and provides full-wave commutation in a 16-SSOP package, ideal for compact switch boards. Silent PWM drive limits radiated EMI that could couple into adjacent high-frequency signal traces. Use this driver for telecom-grade cooling where reliability and silent operation matter.

Principaux différenciateurs
- Silent PWM drive reduces reactive current and EMI (vs Conventional fixed-frequency PWM fan drivers)
- Integrated lock-rotor detection with auto-restart (vs Discrete H-bridge + external timer)
- Wide supply range with explicit 24 V support (vs 12 V-only fan drivers)
Notes de conception
Estimated: at 24 V supply and full-load fan current, the SSOP-16 package dissipates several hundred milliwatts. Provide at least 100 mm^2 of copper under the exposed pad if present, and keep the SSOP-16 paddle area clear of solder mask to maximise theta_JA margin. Place temperature-sensitive analog circuitry away from the driver.
Place input bulk capacitors as close as possible to the supply pins to absorb the reactive current that the fan returns through the H-bridge. Recommended input capacitance is typically a 10 uF ceramic in parallel with a 100 nF high-frequency bypass. Keep the H-bridge output traces short and wide to minimise ringing and EMI, and route the PWM speed command trace away from the H-bridge outputs.
Do not assume the LV8860V family is pin-compatible with the LB11867 family. LV8860V uses 16-SSOP with a PWM command input, while LB11867FV uses SSOP-20 with an analog voltage command. Verify pinout against the manufacturer datasheet ENA1818 before PCB layout finalisation. Also ensure the lock-detection timing matches the rotor inertia of your specific fan.
Keep the analog ground return of the PWM input separated from the power ground return of the H-bridge to avoid noise coupling into the speed command. Use a star-ground topology at the input capacitor ground pad, and connect the SSOP thermal pad to the analog ground rather than the power ground if available.
