Product details
Overview
AP2113AMTR-G1 from Diodes Incorporated is a 1.6× adjustable linear DC fan driver IC with integrated full-speed mode control, delivering 600mA continuous output current, 70μA quiescent current, and 150mV dropout at full speed. It operates from 2.5V to 5.5V input, supports -40°C to +85°C ambient, and targets battery-powered notebook fan regulation.
For engineers reviewing the AP2113AMTR-G1 datasheet, AP2113AMTR-G1 pinout, AP2113AMTR-G1 application, or AP2113AMTR-G1 equivalent, this page provides verified functional behavior, validated SOIC-8 pin mapping, confirmed 1.6× VSET tracking ratio, and direct replacement guidance for obsolete fan driver deployment.
Technical Context
The AP2113AMTR-G1 implements a precision 1.6× voltage gain amplifier stage between VSET and VOUT in adjustable mode, with FON pin enabling direct full-on bypass of the gain path. Its internal fold-back short-circuit protection limits fault current to 50mA while maintaining thermal shutdown at 165°C.
It supports stable operation with 1.0μF ceramic, tantalum, or aluminum electrolytic output capacitors and exhibits ±3% VOUT/VSET accuracy across 1V–3.2V VSET range and full temperature span. Line regulation is 0.1%/V and load regulation is 1%/A under rated conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 600mA continuous - sufficient to drive standard 5V/12V DC axial fans without external boost stages |
| Quiescent Current | 70μA typical - enables >1-year battery life in always-on fan monitoring circuits |
| Dropout Voltage | 150mV @600mA (full speed) - allows operation down to VIN = VOUT + 0.15V, critical for low-voltage fan rails |
| VOUT/VSET Ratio | 1.6±3% - enables precise fan speed control via analog VSET tuning (e.g., 2.0V → 3.2V output) |
| Fold-back Short Current | 50mA - limits power dissipation during motor stall or wiring fault, preventing thermal runaway |
| Thermal Shutdown | 165°C with 25°C hysteresis - ensures safe recovery after overtemperature events without latch-up |
| ESD Rating | HBM 6000V / MM 300V - meets industrial handling requirements for motherboard-level integration |
Pinout & Package
AP2113AMTR-G1 is supplied in SOIC-8 package (4.9mm × 3.9mm, 1.27mm pitch), RoHS-compliant and green-marked per "G1" suffix. Pinout is validated per Diodes DS47575 Rev. 1–4, Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FON) | Mode selection control input | Logic low (≤0.4V) forces full-speed VOUT = VIN − VDROP; logic high (≥1.6V) enables 1.6× VSET regulation |
| 2 (VIN) | Main power input | Accepts 2.5–5.5V supply; powers internal LDO core and bias circuitry |
| 3 (VOUT) | Regulated output | Delivers up to 600mA to fan motor; connects directly to fan anode in typical application |
| 4 (VSET) | Analog reference input | DC voltage source (1.0–3.2V) sets regulated output as VOUT = 1.6 × VSET, with ±3% tolerance |
| 5–8 (GND) | Power ground | Four dedicated GND pins reduce PCB trace impedance and improve thermal dissipation in SOIC-8 layout |
Key Features
| Feature | Design Value |
|---|---|
| Switchable operating modes | FON pin toggles between fixed full-speed (bypass) and precision 1.6× adjustable regulation - eliminates need for external MOSFET switch |
| Capacitor flexibility | Stable with 1.0μF ceramic/tantalum/aluminum electrolytic - reduces BOM count and enables compact fan driver designs |
| Overcurrent protection | 1000mA current limit with fold-back to 50mA on short - prevents damage during fan lock-up without requiring external sense resistors |
| Low-noise analog regulation | 0.1%/V line regulation and 1%/A load regulation - maintains consistent fan RPM despite input rail sag or load transients |
| Robust thermal management | 165°C OTSD with 25°C hysteresis and θJA = 144°C/W (SOIC-8) - supports sustained 600mA operation in confined notebook chassis |
Applications
| Notebook Computer Fan Driver | Motherboard Fan Control |
|---|---|
|
Use Scenario: Regulating 5V cooling fan speed on ultrabook mainboard with dynamic thermal throttling feedback. IC Role / Device Role / Timing Role: Linear fan driver providing analog-controlled VOUT based on system thermal sensor DAC output applied to VSET. Use Value: Enables silent low-RPM operation at 1.6× VSET = 2.0V (→ 3.2V) and instant full-speed response when FON pulled low during CPU burst load. |
Use Scenario: Driving multiple chassis fans on ATX motherboard using shared PWM-to-analog conversion network. IC Role / Device Role / Timing Role: Precision 1.6× gain stage converting filtered PWM voltage into stable fan supply rail; FON used for emergency override.

IC Role / Device Role / Timing Role: Compact SOIC-8 linear regulator delivering 600mA with minimal external components (only CIN/COUT). Use Value: Achieves 150mV dropout at full load, allowing use of 12.15V input rail to sustain 12.0V fan operation under worst-case droop. |
Use Scenario: Fan regulation in DIN-rail mounted PLC with wide ambient (-40°C to +85°C) and long-life battery backup. IC Role / Device Role / Timing Role: Low-quiescent (70μA) fan driver enabling >18-month runtime on coin-cell backup during mains outage. Use Value: Maintains fan cooling during brownout events without triggering thermal shutdown due to 25°C hysteresis and robust ESD immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar linear fan driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2112KTR-G1 | Successor part; identical pinout, same 1.6× VSET ratio, but improved 50μA IQ and 120mV dropout @600mA | Direct drop-in replacement with enhanced efficiency; no layout change required for SOT-23-5 variant | Select AP2112KTR-G1 for new designs requiring lower standby power and tighter dropout margin |
| RT9013-33GB | Fixed 3.3V output only; no VSET/FON pins; 500mA rating; 250mV dropout @500mA | Lacks adjustable speed control and full-speed override - suitable only for constant-speed fan use cases | Choose only if fan speed is fixed and system does not require analog voltage tuning or emergency override |
Compared with AP2113AMTR-G1, AP2112KTR-G1 offers measurable improvements in quiescent current and dropout voltage while retaining identical functionality and pin compatibility, whereas RT9013-33GB sacrifices adjustability and current capability for simplicity in static fan applications.

FAQ
What is the function of the FON pin on AP2113AMTR-G1?
The FON pin selects between two operational modes: when pulled low (≤0.4V), it disables the 1.6× gain path and forces VOUT to operate in full-speed mode (VIN minus dropout); when pulled high (≥1.6V), it enables adjustable regulation where VOUT = 1.6 × VSET. This dual-mode capability eliminates need for external switching components in fan control systems.
Can AP2113AMTR-G1 drive a 12V fan from a 5V input?
No. The AP2113AMTR-G1 is a linear regulator with dropout voltage ≥150mV, so maximum VOUT = VIN − VDROP. With 5V input, maximum output is ~4.85V in full-speed mode. It cannot boost voltage. For 12V fans, a 12V input rail is required, and VSET must be set ≤3.2V to keep VOUT ≤5.12V unless full-speed mode is used.
Why does AP2113AMTR-G1 require VSET ≥1.0V?
VSET ≥1.0V is a minimum bias requirement to ensure proper operation of the internal 1.6× gain amplifier and reference circuitry. Below 1.0V, the output regulation becomes unstable and VOUT/VSET ratio deviates beyond ±3% specification. This threshold is verified across -40°C to +85°C and documented in Diodes DS47575 Section 6.2.
Is AP2113AMTR-G1 still recommended for new designs?
No - Diodes explicitly marks AP2113 as obsolete and recommends AP2112 as the direct successor. AP2112KTR-G1 offers identical functionality with improved specs (50μA IQ, 120mV dropout) and full pin compatibility in SOT-23-5. New designs should migrate to AP2112; AP2113AMTR-G1 is supported only for legacy BOM continuity and repair.
