Product details
Overview
TPIC2810D from Texas Instruments is an 8-channel, I²C-compatible, low-side DMOS power switch IC designed to drive resistive loads such as LEDs in industrial and automotive lighting control systems. It features 40 V drain-to-source voltage rating, 100 mA continuous sink current per channel, 5 Ω typical rDS(on) at 25°C, thermal shutdown protection, and integrated power-up clear. Its SOIC-16 package supports operation from −40°C to 125°C case temperature.
For engineers reviewing the TPIC2810D datasheet, TPIC2810D pinout, TPIC2810D application, or TPIC2810D equivalent, this page delivers verified electrical parameters, I²C protocol behavior, thermal derating curves, output enable timing, and real-world load-switching constraints - all specific to the TPIC2810D variant with D-package and NIPDAU lead finish.
Technical Context
The TPIC2810D implements an 8-bit serial-in/parallel-out shift register fed by an I²C interface with hard-coded group ID (1100) and user-configurable 3-bit device address (A0–A2). Data transfer requires subaddress validation (11H, 22H, or 44H) before loading into the output storage register, enabling precise sequencing of LED bank activation without unintended flicker.
Each of its eight open-drain DMOS outputs operates as a low-side switch with internal current limiting (210 mA peak at TC = 25°C), thermal shutdown activation at 160°C junction temperature, and 3000 V HBM ESD protection on drain terminals. The device does not support inductive load switching and relies on external pull-ups for SDA/SCL lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 40 V - Maximum drain-to-source voltage; defines absolute upper limit for load supply rail when used as low-side switch. |
| IO continuous | 100 mA per channel - Continuous sink current capability per output; derates with temperature and number of active channels. |
| rDS(on) | 5 Ω typical at VCC = 5 V, TC = 25°C - On-resistance directly impacts power dissipation and voltage drop across each switched load. |
| I²C clock frequency | Up to 2 MHz - Supports high-speed bus communication; timing margins validated for 100 kHz, 400 kHz, and 2 MHz modes. |
| Thermal shutdown | 160°C ±10°C - Junction temperature threshold triggering automatic output disable; includes 10–30°C hysteresis for stable recovery. |
| Operating temperature | −40°C to 125°C case - Specifies full functional range for mounting on PCBs in harsh environments without derating. |
| ESD protection | 3000 V HBM on drains, 2000 V HBM on inputs - Enables robust handling during assembly and operation in electrostatic-prone settings. |
Pinout & Package
TPIC2810D is housed in a 16-pin SOIC (D) package with standard JEDEC outline, 1.27 mm pitch, and NIPDAU lead finish. Pin 1 is located at top-left corner (Q1 quadrant in tape-and-reel orientation), with GND at pin 16 and VCC at pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Logic supply input | Provides 3.0–5.5 V power for internal logic and I²C interface; decoupling capacitor required near pin. |
| SDA (Pin 2) | I²C bidirectional data line | Open-drain interface requiring external pull-up; handles subaddress/data transfer and ACK/NACK signaling. |
| DRAIN0–DRAIN7 (Pins 3–6, 11–14) | Power DMOS drain outputs | Eight independent low-side switches; each sinks current to GND when driven high in output register and G = low. |
| A0–A2 (Pins 9–10, 7) | I²C device address inputs | Three binary inputs setting unique 3-bit slave address; enables up to eight TPIC2810D devices on same I²C bus. |
| G (Pin 8) | Global output enable | Active-low control: drives all outputs off when high; enables transparency from storage register to DMOS gates when low. |
| SCL (Pin 15) | I²C clock input | Master-generated clock synchronizing data transfers; rise/fall times specified for 100 kHz–2 MHz operation. |
| GND (Pin 16) | Ground reference | Common return path for logic supply, I²C signals, and all DMOS source terminals (internally tied to GND). |
Key Features
| Feature | Design Value |
|---|---|
| I²C subaddress protocol | Supports three defined commands (11H read/write shift register, 22H transfer to output register, 44H combined write+transfer) - eliminates ambiguous bus states and ensures deterministic output updates. |
| Thermal shutdown with hysteresis | Triggers at 160°C junction temperature with 10–30°C hysteresis - prevents thermal runaway during sustained overload while avoiding oscillation near trip point. |
| Power-up clear circuit | Resets I²C interface and clears all output registers on VCC ramp-up - guarantees known off-state at power-on without external reset circuitry. |
| Current-limited DMOS outputs | 210 mA peak per channel at TC = 25°C, decreasing with rising temperature - provides intrinsic short-circuit protection without external sense resistors. |
| High-voltage drain tolerance | 40 V rated drain-to-source breakdown - allows direct interfacing with 24 V industrial rails and 36 V automotive systems when used with appropriate load impedance. |

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 |
|---|---|---|---|
| TLC59116IPWPR | 16-bit constant-current PWM LED driver with I²C interface; no DMOS outputs - uses internal current sources instead of switch-based sinking. | Requires external current-setting resistors; supports dimming via 12-bit PWM but lacks thermal shutdown and 40 V drain rating. | Choose TLC59116IPWPR when precise LED current matching and analog dimming are required over raw switching speed and high-voltage tolerance. |
| PCA9685PW | 16-channel 12-bit PWM controller with open-drain outputs; logic-level only - no integrated power DMOS transistors or current limiting. | Needs external MOSFETs for >20 mA loads; no built-in thermal protection or ESD hardening on output pins. | Choose PCA9685PW when driving low-power indicators or when full PWM resolution and software-defined fade profiles outweigh integration benefits. |
Compared with TLC59116IPWPR and PCA9685PW, the TPIC2810D offers higher voltage tolerance (40 V vs. 5.5 V logic), integrated power DMOS switches with current limiting, and autonomous thermal shutdown - making it uniquely suited for direct 12–24 V LED load control without supporting components.

FAQ
What is the maximum continuous current per channel for TPIC2810D at 125°C case temperature?
At TC = 125°C, the TPIC2810D supports approximately 75 mA continuous sink current per channel (per Figure 7), down from 100 mA at 25°C. This derating ensures safe operation within thermal limits when multiple outputs are active simultaneously - critical for dense LED array designs where ambient heat buildup occurs.
Can TPIC2810D drive inductive loads such as relays or solenoids?
No, the TPIC2810D is explicitly not recommended for switching inductive loads. Its datasheet states this limitation due to lack of integrated flyback protection; voltage spikes from coil collapse exceed the 40 V VDS rating and may damage the DMOS outputs. Use dedicated relay drivers like ULN2803A or TPIC6B595 for such applications.
How does the TPIC2810D handle I²C address conflicts when multiple devices share the same bus?
The TPIC2810D uses a fixed 4-bit group ID (1100) plus user-configurable 3-bit address (A0–A2), yielding up to eight unique addresses per bus segment. Each TPIC2810D must have distinct A0–A2 logic levels; mismatched configurations cause bus contention or non-response - verified during power-up clear initialization.
What happens to TPIC2810D outputs during a thermal shutdown event?
When junction temperature reaches 160°C, the TPIC2810D disables all eight DMOS outputs immediately and holds them off until temperature falls below the hysteresis threshold (130–150°C). Outputs remain latched off even if G pin is asserted low - ensuring fail-safe behavior during overtemperature faults.
Is external pull-up resistance required for SDA and SCL pins on TPIC2810D?
Yes, both SDA and SCL pins are open-drain and require external pull-up resistors. Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and target I²C speed (100 kHz to 2 MHz); TI recommends 4.7 kΩ for standard-mode operation with ≤400 pF total bus capacitance.
