Product details
Overview
CDM10V4XTSA1 from Infineon Technologies is a fully integrated 0–10 V dimming interface IC in SOT-23-6 package, designed to convert analog dimmer voltage (0–10 V) into a 2 kHz, 5 mA PWM current signal for driving external optocouplers in LED drivers. It features 100 µA dimmer bias current, dim-to-off functionality below 1 V, and ±3% dimming accuracy across temperature and unit variation.
For engineers reviewing the CDM10V4XTSA1 datasheet, CDM10V4XTSA1 pinout, CDM10V4XTSA1 application, or CDM10V4XTSA1 equivalent, this device serves as a drop-in replacement for discrete 0–10 V interface circuits-reducing BOM count, PCB footprint, and inter-unit calibration effort in commercial luminaires, troffers, and DALI-compatible lighting systems.
Technical Context
The CDM10V4XTSA1 integrates an internal LDO, bandgap reference, 8-bit ADC, digital FSM, and PWM generator with current-source output. Its analog front-end senses Rdim+ voltage (0–10 V), digitizes it, and maps linearly to 0–100% PWM duty cycle at fixed 2 kHz frequency.
It delivers a regulated 5 mA sink current on Iout with ±10% tolerance, supports 11–25 V Vcc input, operates from –40 °C to +105 °C ambient, and includes UVLO and ESD protection (1500 V HBM, 500 V CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Vcc Range | 11–25 V: Enables direct use with common 12/24 V lighting rails without external regulation. |
| PWM Frequency | 2 kHz ±6%: Eliminates audible noise while ensuring compatibility with standard optocoupler response times. |
| Iout Current | 5 mA ±10%: Provides sufficient drive strength for standard PC817/PC818-class optocouplers without external amplification. |
| Dimmer Bias Current | 100 µA: Matches typical 0–10 V dimmer output impedance, minimizing loading error and linearity drift. |
| Dimming Accuracy | ±3%: Ensures consistent light output across units and temperature without per-unit trimming. |
| Dim-to-Off Threshold | <1 V: Guarantees full LED shutdown in low-signal or open-circuit dimmer failure conditions. |
| ESD Robustness | 1500 V HBM: Protects against handling-induced discharge during assembly and field service. |
Pinout & Package
SOT-23-6 package: 2.9 mm × 1.6 mm × 1.1 mm body, thermally enhanced pad, RoHS-compliant, JEDEC qualified for industrial lighting applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 VCC | Supply Input | Accepts 11–25 V DC; powers internal LDO and logic; requires local 100 nF decoupling. |
| 2 GND | Ground Reference | Primary return path for internal circuitry and Iout current sink. |
| 3 Iout | PWM Current Output | Active-low 5 mA PWM sink output; connects directly to optocoupler anode. |
| 4 NC | No Connect | Internally tied to GND; must be externally connected to ground for thermal and noise stability. |
| 5 NC | No Connect | Internally tied to GND; must be externally connected to ground for thermal and noise stability. |
| 6 Rdim+ | Dimmer Voltage Sense | Inputs 0–10 V analog signal; sources 100 µA bias current; max voltage = VCC + 0.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated 0–10 V interface | Replaces ≥7 discrete components (op-amps, transistors, resistors, capacitors) in legacy designs. |
| Digital signal processing core | 8-bit ADC + FSM ensures <±3% dimming linearity and eliminates analog drift over time/temperature. |

IC Role / Device Role / Timing Role: Acts as analog output stage-accepts DAC voltage from microcontroller and converts to standardized 0–10 V compliant current-mode signal. Use Value: Enables single-chip DALI-to-analog translation without external current buffers or feedback loops. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 0–10 V dimming interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI UCC27511DR | High-speed gate driver (4 A peak); no built-in ADC, PWM generator, or dimmer bias current. | Requires external op-amp, comparator, and current source to replicate CDM10V4XTSA1 function. | Only suitable when existing design already implements analog signal conditioning and needs only fast switching. |
| ON Semi NCL30160DR2G | Dedicated LED driver with integrated 0–10 V input; lacks isolated current-output capability and requires optocoupler bypass. | Directly drives LEDs but cannot interface to third-party LED drivers with optocoupler-based dim inputs. | Preferred only for new, self-contained LED modules-not for retrofit or system-level dimming interface roles. |
Compared with UCC27511DR and NCL30160DR2G, the CDM10V4XTSA1 uniquely combines precision analog sensing, digital PWM generation, and 5 mA current-source output in one SOT-23-6 package-enabling true plug-and-play 0–10 V interface functionality without supporting circuitry.

FAQ
What is the minimum Rdim+ voltage required to activate dimming?
The CDM10V4XTSA1 enters active dimming mode at Rdim+ ≥ 1 V. Below 1 V, it asserts dim-to-off behavior-driving Iout to zero regardless of PWM timing. This threshold is guaranteed across –40 °C to +105 °C ambient and does not require external hysteresis or pull-up components.
Can CDM10V4XTSA1 drive optocouplers directly without external components?
Yes-the 5 mA ±10% Iout current source is designed to directly drive standard PC817, TLP185, or VO615A optocouplers. No series resistor or buffer transistor is needed. A 4.7 nF capacitor on Rdim+ is recommended for noise filtering, and a Schottky diode (e.g., MMSD301T1G) is advised if Rdim+ may exceed VCC during active dimming.
Does CDM10V4XTSA1 support reverse polarity protection on VCC or Rdim+?
No-the device has no internal reverse-polarity protection. VCC must be connected with correct polarity (11–25 V positive to Pin 1); applying reverse voltage will damage the IC. Rdim+ pin tolerates up to VCC + 0.5 V but not negative voltage-external clamping diodes are required in systems prone to wiring errors or inductive kickback.
How does thermal performance scale with PWM duty cycle and Vcc?
Power dissipation ranges from 6.05 mW (1% duty) to 160 mW (100% duty at 25 V Vcc). The SOT-23-6 package requires ≥25 mm² copper pour connected to Pin 2 (GND) for reliable operation at 100% duty above 60 °C ambient, per Figure 3 in the Infineon datasheet V1.1.
