Product details
Overview
AP2113BMTR-G1 from Diodes Incorporated is a 600mA low-dropout linear regulator optimized as a 1.6× adjustable DC fan driver, featuring 70μA quiescent current, 150mV dropout at full speed mode (600mA), and dual-mode operation (adjustable/fully-on) controlled by the FON pin. It operates from 2.5V–5.5V input and supports ceramic/tantalum/aluminum output capacitors down to 1.0μF.
For engineers reviewing the AP2113BMTR-G1 datasheet, AP2113BMTR-G1 pinout, AP2113BMTR-G1 application, or AP2113BMTR-G1 equivalent, key selection criteria include VOUT/VSET = 1.6±3% tracking accuracy, fold-back short-circuit protection (50mA), thermal shutdown at 165°C, and SOIC-8/SOT-23-5 package compatibility for notebook fan control and motherboard power management.
Technical Context
The AP2113 implements a precision 1.6× voltage-tracking architecture where VOUT = 1.6 × VSET (min VSET = 1.0V), constrained by VIN − VDROP. In adjustable mode (FON = high), dropout is 200mV @ 600mA; in full-speed mode (FON = low), dropout drops to 150mV @ 600mA with fixed VOUT ≈ VIN.
It integrates overcurrent limiting (1000mA trip), fold-back short-circuit protection (50mA sustained), OTSD (165°C with 25°C hysteresis), and ESD robustness (HBM 6000V/MM 300V). Stable with 1.0μF output capacitance across ceramic, tantalum, and aluminum electrolytic types.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 600mA continuous - sufficient to drive standard 5V/12V DC cooling fans without external boost. |
| Quiescent Current | 70μA typical - enables long battery runtime in portable fan-controlled systems. |
| VOUT/VSET Ratio | 1.6 ± 3% - enables precise, programmable fan voltage scaling from 1.0V–3.2V VSET inputs. |
| Dropout Voltage | 150mV @ 600mA (full-speed mode) - minimizes power loss and heat rise when VIN is near VOUT. |
| Short-Circuit Protection | Fold-back limit of 50mA - limits fault power dissipation and prevents thermal runaway during VOUT short. |
| Thermal Shutdown | 165°C with 25°C hysteresis - ensures safe recovery after overload without manual reset. |
| Operating Temp Range | −40°C to +85°C ambient - validated for motherboard and peripheral card environments. |
Pinout & Package
AP2113BMTR-G1 is supplied in SOIC-8 package (M suffix), with lead-free, RoHS-compliant "G1" marking and tape-and-reel packaging (TR). Thermal resistance θJA = 144°C/W (no heatsink).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FON) | Mode control input | Logic low enables full-speed mode (VOUT ≈ VIN); logic high enables 1.6× adjustable mode. |
| 2 (VIN) | Input supply rail | Accepts 2.5V–5.5V; powers internal LDO and bias circuitry; requires ≥1μF input capacitor. |
| 3 (VOUT) | Regulated output | Delivers up to 600mA; stable with 1.0μF ceramic/tantalum/aluminum output capacitor. |
| 4 (VSET) | Voltage reference input | DC voltage input (≥1.0V) sets VOUT = 1.6 × VSET; draws only 1μA bias current. |
| 5–8 (GND) | Power ground | Common return path for VIN, VOUT, VSET, and FON; multiple pins reduce ground impedance. |
Key Features
| Feature | Design Value |
|---|---|
| 1.6× VOUT/VSET tracking | Enables accurate, resistor-free fan voltage scaling-eliminates need for feedback resistors or DACs. |
| Switchable full-speed mode | FON pin forces VOUT ≈ VIN for maximum fan torque during startup or thermal emergencies. |
| Low-IQ + fold-back protection | 70μA quiescent current plus 50mA short-circuit clamp reduces standby power and fault energy. |
| Capacitor-flexible stability | Stable with 1.0μF ceramic, tantalum, or aluminum electrolytic output caps-reduces BOM cost and footprint. |
| Integrated OTSD with hysteresis | 165°C shutdown + 25°C hysteresis prevents cycling and enables automatic safe recovery after cooling. |
Applications
| Notebook Computer Fan Driver | Motherboard VRM Auxiliary Power |
|---|---|
|
Use Scenario: Regulating voltage to 5V/12V axial/centrifugal cooling fans in ultrabooks and thin-and-light laptops. IC Role / Device Role / Timing Role: Primary fan voltage controller with dynamic speed scaling via VSET and emergency full-on override via FON. Use Value: Enables silent low-speed operation (via 1.6× scaling from low VSET) and instant full-cooling response (FON=low), extending battery life while maintaining thermal safety. |
Use Scenario: Providing dedicated, low-noise 3.3V/5V bias for chipset fan headers, PCIe slot fans, or VRM thermal sensors on ATX/mATX motherboards. IC Role / Device Role / Timing Role: Standalone LDO supplying regulated fan power independent of main CPU/GPU VRMs. Use Value: Isolates fan power from noisy digital rails, avoids fan stall due to VRM droop, and simplifies layout with single-cap stability. |
| Peripheral Card Cooling | Embedded Industrial Controller Fans |
|
Use Scenario: Driving cooling fans on PCIe add-in cards (GPU accelerators, FPGA compute cards, NVMe RAID controllers). IC Role / Device Role / Timing Role: Local fan regulator co-located with heat-generating ICs, minimizing trace inductance and voltage drop. Use Value: Ensures consistent fan speed despite local board-level voltage fluctuations; fold-back protection prevents card-level thermal cascade failure. |
Use Scenario: Controlling fans in DIN-rail mounted PLCs, HMIs, or edge AI gateways operating in −40°C to +85°C industrial enclosures. IC Role / Device Role / Timing Role: Temperature-resilient fan driver with guaranteed operation across full industrial temperature range and ESD-hardened I/O. Use Value: Eliminates need for external thermal monitoring ICs-OTSD and wide temp range provide self-contained thermal safety. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DC fan driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2112KTR-G1 | Successor part; identical pinout, same 1.6× tracking, but improved PSRR and tighter VOUT/VSET tolerance (±2%). | Direct replacement with enhanced noise rejection for fan drivers in EMI-sensitive systems (e.g., medical imaging controllers). | Select AP2112 for new designs requiring higher PSRR or longer product lifecycle support. |
| RT9193-33GB | Fixed 3.3V LDO (no VSET/FON); 500mA output; 60μA IQ; no fold-back protection (only current limit). | Suitable only for fixed-voltage fan applications without speed scaling or short-circuit resilience requirements. | Choose only if fan voltage is fixed and system lacks thermal fault containment needs. |
Compared with AP2113BMTR-G1, AP2112KTR-G1 offers superior PSRR and tighter ratio tolerance for noise-sensitive fan control, while RT9193-33GB sacrifices adjustability and fold-back protection for lower IQ and cost in fixed-voltage use cases.

FAQ
What is the minimum VSET voltage required for proper 1.6× regulation?
The AP2113 requires VSET ≥ 1.0V to guarantee VOUT = 1.6 × VSET within ±3% tolerance. Below 1.0V, regulation becomes unstable and VOUT may collapse or track nonlinearly. This threshold is specified in the Absolute Maximum Ratings table and confirmed in Figure 7 (VOUT vs. VSET).
Can AP2113BMTR-G1 drive a 12V fan from a 5V input?
No. The AP2113 is a linear regulator-not a boost converter-so VOUT cannot exceed VIN. With 5V input, maximum VOUT is VIN − VDROP ≈ 4.85V (full-speed mode). For 12V fans, a switching regulator or external boost stage is required.
How does fold-back short-circuit protection behave during a VOUT-to-GND fault?
During VOUT short, output current drops to 50mA (fold-back limit) and remains there until fault clears or thermal shutdown activates at 165°C. This contrasts with constant-current limiting, reducing power dissipation (P = 50mA × VOUT) and preventing destructive overheating in sustained faults.
Is AP2113BMTR-G1 pin-compatible with AP2112KTR-G1?
Yes-AP2112KTR-G1 uses identical SOIC-8 and SOT-23-5 footprints, pin assignments, and functional pin behavior (FON, VSET, VIN, VOUT, GND). It is a direct drop-in replacement with improved specs, as confirmed in Diodes' AP2112 datasheet and migration notice.
