Product details
Overview
TPIC2810DG4 from Texas Instruments is an 8-channel, I²C-compatible, low-side DMOS power switch IC designed to drive resistive loads such as LEDs. It features 40 V drain-source breakdown voltage, 100 mA continuous sink current per channel, 5 Ω typical rDS(on), thermal shutdown protection, and integrated power-up clear. It operates across −40°C to 125°C and targets LED driver modules in industrial control panels.
For engineers reviewing the TPIC2810DG4 datasheet, TPIC2810DG4 pinout, TPIC2810DG4 application, or TPIC2810DG4 equivalent, key selection criteria include I²C address configurability (A0–A2), open-drain output architecture with 210 mA pulsed current limit, thermal shutdown setpoint at 160°C, and SOIC-16 package compatibility with standard PCB layouts.
Technical Context
The TPIC2810DG4 integrates an 8-bit serial-in/parallel-out shift register with an 8-bit D-type storage register, both controlled via a standard I²C bus (SCL/SDA). Data transfer requires verification of fixed group ID (1100) and user-defined 3-bit device address (A0–A2), enabling up to eight devices on one bus.
Its output stage comprises eight independent low-side DMOS transistors with internal current limiting (210 mA at TC = 25°C, derated with temperature), ESD protection (3000 V HBM on drains), and thermal shutdown that disables all outputs when die temperature exceeds 160°C. Power-up clear ensures deterministic off-state initialization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS Rating | 40 V - Supports LED strings with up to 10× white LEDs (3.2 V each) in series without external clamping. |
| IO Continuous | 100 mA per channel - Sufficient for driving high-brightness indicator LEDs at full brightness with minimal thermal margin. |
| rDS(on) | 5 Ω typical at VCC = 5 V, TC = 25°C - Limits conduction loss to ≤50 mW per channel at 100 mA, reducing board-level heating. |
| I²C Clock Speed | Up to 2 MHz - Enables rapid configuration updates in real-time lighting control systems with <500 ns timing margins. |
| Thermal Shutdown | 160°C setpoint with 10–30°C hysteresis - Prevents latch-up during sustained overload while allowing recovery without power cycle. |
| Operating Temperature | −40°C to 125°C case temperature - Qualified for under-hood automotive lighting controllers and industrial HMIs. |
| ESD Protection | 3000 V HBM on drain pins - Eliminates need for external TVS diodes in moderate-noise factory environments. |
Pinout & Package
TPIC2810DG4 is housed in a 16-pin SOIC (D) package with standard 1.27 mm pitch, compatible with automated assembly and IPC-7351B footprint D_300X190X100_P1.27_MM.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Logic supply input | Accepts 3.0–5.5 V; powers internal logic, I²C interface, and gate drivers - must be decoupled with ≥100 nF ceramic near pin. |
| SDA (Pin 2) | I²C bidirectional data line | Open-drain, requires external pullup (typically 2.2–10 kΩ); supports multi-master arbitration and clock stretching. |
| DRAIN0–DRAIN7 (Pins 3–6, 11–14) | Low-side DMOS drain outputs | Eight independent sink switches; each connects load to GND when driven high in output register - no internal freewheeling path. |
| A0–A2 (Pins 9–10, 7) | I²C device address inputs | Hardwired logic inputs (VCC/GND) to select one of eight unique slave addresses (0x40–0x47) on shared bus. |
| G (Pin 8) | Global output enable | Active-low; forces all outputs OFF regardless of register state - used for emergency shutdown or power sequencing. |
| GND (Pin 16) | Power and signal reference | Common return for logic, I²C, and all DMOS sources - must be low-impedance plane to avoid ground bounce during switching. |
| SCL (Pin 15) | I²C clock input | Input-only, edge-triggered; tolerates 0–5.5 V swing; requires external pullup matching SDA for rise time compliance. |
Key Features
| Feature | Design Value |
|---|---|
| I²C subaddress protocol (11H/22H/44H) | Enables atomic write-and-latch (44H), separate shift+transfer (11H+22H), or read-back (11H R) - prevents partial-output glitches during update. |
| Thermal shutdown with hysteresis | Shuts down all outputs at 160°C and re-enables only after cooling ≥10°C - avoids oscillation during transient overloads. |
| Power-up clear circuit | Resets shift and output registers to 00H on VCC ramp, ensuring all channels start OFF - eliminates undefined startup states. |
| Configurable 3-bit I²C address | A0–A2 pins allow eight unique addresses (0x40–0x47) on single bus - simplifies multi-device LED matrix control without software address mapping. |
| 210 mA pulsed current limit per channel | Hardware-enforced peak limit (≤100 µs, ≤2% duty) protects against short-circuit faults without external current-sense components. |
Applications
| Industrial HMI Backlight Control | Automotive Cabin LED Indicator Panel |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side I²C LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC59116IPWR | 16-bit constant-current PWM sink driver; I²C address fixed at 0x60–0x6F; no thermal shutdown; rDS(on) not specified. | Optimized for uniform LED brightness control via 12-bit PWM; unsuitable for simple on/off or high-current (>25 mA) discrete LEDs. | Choose TLC59116IPWR only when precise dimming is required and thermal fault protection is handled externally. |
| PCA9674APW | 8-bit I²C GPIO expander with push-pull outputs; max 25 mA per pin; no DMOS power switching; no current limiting or thermal protection. | Designed for logic-level signal routing, not power switching; cannot drive LEDs directly above 20 mA without external buffers. | Use PCA9674APW for digital control signals only; TPIC2810DG4 remains necessary for direct LED sink capability above 25 mA. |
Compared with TLC59116IPWR and PCA9674APW, TPIC2810DG4 uniquely combines I²C address flexibility, 100 mA per-channel sink capability, hardware current limiting, and thermal shutdown - making it the only drop-in solution for robust, high-current LED indicator systems without added protection circuitry.

FAQ
What is the maximum continuous current per channel for TPIC2810DG4?
The TPIC2810DG4 supports 100 mA continuous sink current per channel at TC = 25°C. This rating decreases with increasing case temperature - e.g., ~75 mA at TC = 85°C and ~50 mA at TC = 125°C - as defined in Figure 7 of the SLIS109A datasheet. Derating must be applied for multi-channel operation to maintain safe junction temperature.
Does TPIC2810DG4 support standard I²C addressing and protocols?
Yes, TPIC2810DG4 implements full I²C compliance including START/STOP conditions, ACK/NACK handshaking, and 7-bit addressing. Its fixed group ID (1100) plus user-configurable A0–A2 pins yield addresses 0x40–0x47. Subaddress commands (11H/22H/44H) enable atomic writes, register reads, and safe output updates without glitching - all verified in the SLIS109A protocol definition section.
Can TPIC2810DG4 drive inductive loads such as relays or solenoids?
No, the TPIC2810DG4 is explicitly not recommended for switching inductive loads. Its DMOS outputs lack internal flyback diodes or clamp circuits, and the datasheet warns against relay/solenoid use due to voltage spikes exceeding the 40 V VDS rating. For inductive loads, TI recommends dedicated drivers like ULN2803A or TPIC6B595.
What thermal protection features does TPIC2810DG4 include?
The TPIC2810DG4 incorporates a die-temperature sensor that triggers thermal shutdown at 160°C, disabling all eight DMOS outputs. Recovery occurs only after junction temperature falls below the hysteresis threshold (10–30°C lower). This behavior is fully characterized in the "Thermal Shutdown" section of SLIS109A and validated across −40°C to 125°C operating range.
Is TPIC2810DG4 pin-compatible with other variants in the TPIC2810 family?
Yes, TPIC2810DG4 shares identical SOIC-16 (D) package dimensions, pinout, and electrical characteristics with TPIC2810D, TPIC2810DR, and TPIC2810DRG4. The "G4" suffix denotes RoHS-compliant NiPdAu lead finish and tape-and-reel packaging - functionally interchangeable in all designs using the D package footprint.
