Product details
Overview
AP1347SL-13 from Anachip Corp. is a two-coil brushless DC fan motor predriver IC with integrated Hall sensor interface, lock shutdown and automatic restart logic, and dual driver outputs (OUT1/OUT2) delivering up to 70mA per channel. It operates from 4V to 28V, supports rotation detection (RD) output, and is housed in an SOP-8L package for high-voltage cooling systems in industrial power supplies.
For engineers reviewing the AP1347SL-13 datasheet, AP1347SL-13 pinout, AP1347SL-13 application, or AP1347SL-13 equivalent, key selection criteria include RD output functionality (vs. FG-only AP1346), thermal shutdown behavior, Hall input hysteresis (±3–15mV), CT timing capacitor control, and SOP-8L pin compatibility with two-coil BLDC fan layouts.
Technical Context
The AP1347SL-13 implements a dedicated Hall-amp-based commutation controller for two-phase BLDC fans, with separate HS(+) and HS(−) differential Hall inputs enabling robust rotor position sensing. Its internal control logic integrates lock detection, automatic restart recovery, and a clamp voltage (1.6–2.4V) for Hall signal conditioning.
It features a CT pin that sets oscillator frequency via external capacitor, driving predriver stages for OUT1 and OUT2 with complementary timing. The RD output provides open-drain status indication of motor rotation presence-distinct from AP1346's FG speed-pulse output-making it suitable for safety-critical fan presence monitoring.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 4V to 28V - supports wide-input industrial and telecom power rails without external regulation |
| Output Current | 70mA max per OUT1/OUT2 - drives gate resistors of external N-channel MOSFETs in half-bridge fan drivers |
| Hall Hysteresis | ±3mV to ±15mV - ensures noise-immune commutation under EMI-prone motor environments |
| Operating Temp | −30°C to +85°C - rated for enclosed chassis and high-ambient server/PSU cooling applications |
| RD Output Type | Open-drain, ≤0.5V @ 5mA - directly interfaces with microcontroller GPIO for fail-safe rotation monitoring |
| Thermal Shutdown | Integrated - disables outputs at junction temperature >150°C and auto-restarts when cooled |
| CT Timing Range | Charge/discharge ratio 32–48 - enables precise tuning of commutation frequency via capacitor value |
Pinout & Package
SOP-8L (Small Outline Package, 8-pin, lead-free, 1.27mm pitch), dimensions per JEDEC MS-012, body width 3.9mm, height 1.45mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| GND | Ground reference | Common return for Hall amp, logic, and driver stages; low-impedance path critical |
| HS(+) | Hall sensor positive input | Differential input for Hall element output; referenced to HS(−) for noise rejection |
| HS(−) | Hall sensor negative input | Complementary Hall input; enables common-mode noise cancellation |
| FG/RD | Function-selectable I/O | Configured as RD (rotation detect) for AP1347; open-drain status flag |
| CT | Oscillator timing node | Connects external capacitor to set commutation frequency; charge/discharge current ratio defined |

| OUT2 | Driver output 2 | High-current sink/source for coil 2 drive; complements OUT1 for two-phase excitation |
Key Features
| Feature | Design Value |
|---|---|
| Lock shutdown + auto-restart | Halts outputs during stall and resumes operation within milliseconds after mechanical clearance |
| RD output (AP1347-specific) | Asserts low when rotation confirmed; eliminates need for external pulse counting or edge detection |
| Integrated thermal protection | Shuts down before junction exceeds safe limit; prevents latch-up or bond-wire failure |
| Hall input hysteresis tuning | ±3–15mV window ensures reliable switching across temperature and Hall sensor variance |
| SOP-8L lead-free packaging | RoHS-compliant, reflow-suitable footprint compatible with automated SMT assembly lines |
Applications
| Server Power Supply Cooling | Industrial PLC Fan Control |
|---|---|
Use Scenario: Forced-air cooling of 1U/2U server PSUs operating at 50–70°C ambient with continuous duty cycle. IC Role / Device Role / Timing Role: Pre-driver controlling two-coil BLDC fan via Hall feedback; RD output feeds BMC for real-time fan presence verification. Use Value: Eliminates discrete Hall comparator and logic, reducing BOM count by 4 components while ensuring stall recovery without host intervention. | Use Scenario: Fan management in sealed industrial PLC enclosures exposed to dust, vibration, and wide temperature swings. IC Role / Device Role / Timing Role: Motor controller interfacing with analog Hall sensor; RD signal triggers watchdog timeout if rotation ceases unexpectedly. Use Value: Enables fail-safe shutdown of downstream systems upon fan stall, meeting IEC 61508 functional safety requirements. |
| Telecom Rectifier Modules | Medical Imaging Power Systems |
Use Scenario: Redundant cooling in -48V telecom rectifiers where fan reliability directly impacts system uptime. IC Role / Device Role / Timing Role: Dual-output predriver managing two independent fan coils; RD output logged by system controller for predictive maintenance. Use Value: Provides deterministic stall detection and recovery, reducing unscheduled field service calls by confirming mechanical integrity. | Use Scenario: Thermal management of high-power X-ray generator inverters requiring silent, reliable airflow. IC Role / Device Role / Timing Role: Hall-commutated predriver with thermal shutdown protecting against overheating during extended imaging sessions. Use Value: Prevents thermal runaway in confined spaces by halting fan drive before PCB damage occurs, extending system MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar two-coil BLDC fan predriver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP1346SL-13 | Shares identical pinout and Hall interface but outputs FG (speed pulses) instead of RD (rotation detect) | Used where tachometer feedback is needed for closed-loop speed control, not presence verification | Select AP1346SL-13 only when speed measurement-not stall detection-is the primary requirement |
| TB6612FNG | Higher output current (1.2A), dual H-bridge, no integrated Hall amp or RD/FG logic; requires external Hall signal conditioning | Supports bidirectional control and higher-power motors but increases system complexity and component count | Choose TB6612FNG only when driving larger fans (>10W) or requiring direction reversal capability |
Compared with AP1346SL-13, AP1347SL-13 delivers dedicated rotation status rather than speed pulses; versus TB6612FNG, it reduces design effort for basic two-coil fans but lacks H-bridge flexibility and current drive headroom.

FAQ
What is the function of the CT pin on AP1347SL-13?
The CT pin connects to an external timing capacitor that sets the internal oscillator frequency governing commutation timing. Its charge/discharge current ratio (32–48) determines frequency stability across voltage and temperature. A typical 1nF capacitor yields ~25kHz commutation, adjustable for fan acoustic optimization or torque response.
Can AP1347SL-13 drive a three-coil BLDC fan?
No. AP1347SL-13 is specifically designed for two-coil (single-phase excitation) brushless DC fans with complementary OUT1/OUT2 outputs. Three-coil (three-phase) fans require six-step commutation and three independent half-bridges, which this IC does not support. Use dedicated three-phase predrivers like MP6532 or STSPIN220 instead.
Is the RD output active-high or active-low?
The RD output is open-drain and active-low: it pulls to GND when rotation is detected and floats (high-impedance) when stalled or unpowered. A pull-up resistor (typically 10kΩ to VCC) is required to generate a logic-high idle state. This matches standard microcontroller interrupt inputs and simplifies stall-detection firmware.
Does AP1347SL-13 require external MOSFETs?
Yes. AP1347SL-13 is a predriver only-it provides logic-level gate drive signals (OUT1/OUT2) but lacks integrated power transistors. External N-channel MOSFETs (e.g., Si2302, DMN2004) must be used in half-bridge configurations to switch the fan coils. The 70mA output current rating is sufficient for typical 10–100Ω gate resistors.
