Product details
Overview
BCR602XTSA1 from Infineon is a 60 V linear LED controller IC with hot-plug and dimming capability, regulating LED current via external NPN or NMOS driver transistors. It delivers ±3% LED current precision, suppresses AC supply ripple, and provides overtemperature protection (OTP) that reduces current to 30% at junction temperature threshold. Used in LED replacement lamps and light engines.
For engineers reviewing the BCR602XTSA1 datasheet, BCR602XTSA1 pinout, BCR602XTSA1 application, or BCR602XTSA1 equivalent, key selection factors include its 8–60 V input range, MFIO-based analog/PWM/resistor dimming, DRV output drive capability, thermal derating behavior, and SOT23-6 package constraints for high-power linear LED control.
Technical Context
The BCR602XTSA1 implements a voltage-controlled current regulation loop using an external sense resistor (Rsense) and driver transistor, with feedback taken at VSENSE. Its MFIO pin supports three dimming modes-resistive (via Rset), analog DC (0.2–3.3 V), and PWM (0–100% duty cycle)-with dedicated internal current sources and hysteresis for stable low-level dimming.
Hot-plug protection enables live insertion/removal of LED loads without system interruption, while overtemperature protection triggers progressive current reduction starting at TJ ≥ 150 °C (typical lower limit), resuming full current only after hysteresis recovery. The DRV output drives base/gate with up to –4 mA sink capability under defined thermal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 8 V to 60 V - supports wide-input industrial LED drivers without auxiliary regulation |
| LED Current Accuracy | ±3% - ensures consistent luminous output across units and temperature |
| Dimming Resolution | 3% analog min / 1% PWM min - enables smooth low-end dimming in architectural and residential lighting |
| Overtemperature Threshold | 150 °C (lower spec limit) - initiates current foldback before permanent thermal damage |
| Ripple Suppression | AC supply ripple suppression - maintains constant LED current despite input voltage variation, improving light quality |
| MFIO Input Range | 0.2 V to 5.0 V - compatible with standard MCU GPIOs and DAC outputs for analog dimming |
| Package Thermal Resistance | 290 K/W (no copper pour) - defines maximum continuous LED current based on PCB layout and ambient temperature |
Pinout & Package
BCR602XTSA1 is housed in PG-SOT23-6 (JEDEC TO-236AB), a surface-mount plastic package with 0.95 mm pitch, optimized for thermal dissipation in compact LED modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - DRV | Driver Output | Sinks up to –4 mA to control base/gate of external NPN or NMOS transistor; requires external pull-up or gate resistor |
| 2 - GND | Ground Reference | Common return path for internal circuitry and Rsense; must be low-impedance connection to minimize sensing error |
| 3 - VSENSE | Current Sense Input | Monitors voltage drop across external Rsense; max 3.6 V input limits sense resistor value for given LED current |
| 4 - MFIO | Multifunction I/O | Accepts Rset, analog DC (0.2–3.3 V), or PWM signals; internal 20 µA current source enables resistor dimming |
| 5 - TEST | Factory Test Pin | Must remain open or connected to ground via >1 MΩ resistor; not for user circuit functions |
| 6 - VS | Supply Input | Primary power input (8–60 V); internal LDO powers core logic; power dissipation scales with (VS − VLED) × ILED |
Key Features
| Feature | Design Value |
|---|---|
| Hot-plug protection | Enables safe live connection/disconnection of LED loads without interrupting system operation or damaging IC |
| Triple-mode dimming interface | Single MFIO pin supports resistor-set, analog voltage, and PWM dimming - reduces external component count and board space |
| AC ripple suppression | Compensates for input voltage fluctuations to maintain stable LED current - eliminates visible flicker in line-powered applications |
| Overtemperature foldback | Reduces LED current to 30% at TJ ≥ 150 °C and restores full current only after hysteresis - prevents thermal runaway without shutdown |
| External transistor flexibility | Supports both NPN BJTs (up to ~750 mA with hFE = 75) and NMOSFETs (higher current, lower conduction loss) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar linear LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL8862SP-13 | Switching buck LED driver (not linear); requires inductor, higher efficiency but generates EMI | Preferred for >1 W LED loads where thermal density prohibits linear solution | Select when efficiency >85% and thermal budget <15 °C rise are mandatory |
| LM3409HVMM/NOPB | High-voltage buck controller (6–75 V); external MOSFET + inductor; no integrated dimming logic | Requires external PWM generator or DAC for dimming; no native analog dimming at pin | Select when design requires programmable frequency, sync capability, or multi-string control |
Compared with AL8862SP-13 and LM3409HVMM/NOPB, BCR602XTSA1 offers simpler BOM, zero EMI, and native triple-mode dimming-but trades off efficiency and thermal headroom above ~350 mA in SOT23-6. Best suited for cost-sensitive, low-to-mid power (<1.5 W), noise-sensitive LED applications.

FAQ
What external components are mandatory for basic BCR602XTSA1 operation?
Mandatory components include: an external current-sense resistor (Rsense) between LED cathode and GND, an external driver transistor (NPN or NMOS), and a bypass capacitor (≥100 nF) between VS and GND. No inductor or transformer is required. The MFIO pin may be left unconnected if dimming is not used, but Rset or dimming signal must be added for adjustable current.
How does the BCR602XTSA1 handle overtemperature events without shutting down?
When junction temperature reaches the lower OTP threshold (~150 °C), BCR602XTSA1 reduces LED current to 30% of nominal and holds it there until temperature drops below hysteresis (typically ~140 °C), then fully restores current. This foldback behavior avoids abrupt turn-off, maintains illumination during transient overheating, and protects both LED and IC without requiring external thermal monitoring circuitry.
Can the BCR602XTSA1 drive multiple parallel LED strings?
No - BCR602XTSA1 regulates current through a single external sense resistor, so it controls total current through one series string or one parallel group with matched forward voltages. Driving multiple independent strings requires separate BCR602XTSA1 units per string or a multi-channel controller; shared current sensing across unmatched strings causes current imbalance and potential thermal runaway.
Is the TEST pin required for normal operation?
No - the TEST pin is reserved for factory testing and must not be connected to ground or driven actively. It should be left floating or pulled to GND via a resistor >1 MΩ. Connecting it directly to GND may impair functionality or cause undefined behavior; it has no role in regulation, dimming, or protection circuits.
