Product details
Overview
TPIC2810DR from Texas Instruments is an 8-channel, I²C-controlled, low-side DMOS power switch IC designed for driving resistive loads such as LEDs. It features 40 V drain-to-source breakdown voltage, 100 mA continuous sink current per channel, 5 Ω typical rDS(on) at VCC = 5 V and TC = 25°C, thermal shutdown protection at 160°C, and operates across −40°C to 125°C case temperature range.
For engineers reviewing the TPIC2810DR datasheet, TPIC2810DR pinout, TPIC2810DR application, or TPIC2810DR equivalent, this device is selected for LED matrix control, industrial status indication, and low-voltage logic-level load switching where I²C addressability, integrated current limiting, and robust ESD protection (3000 V on drains) are required.
Technical Context
The TPIC2810DR integrates an 8-bit serial-in/parallel-out shift register with an 8-bit D-type output storage register, both controlled via a standard I²C interface (SCL/SDA) supporting up to 400 kHz clock frequency. Addressing uses hard-coded group ID (1100) plus user-configurable A0–A2 pins, enabling up to eight devices on one bus.
Each of the eight open-drain DMOS outputs provides low-side switching with 210 mA pulsed current limit (TC = 25°C), decreasing with junction temperature rise, and includes internal thermal shutdown that disables all outputs above 160°C with 10–30°C hysteresis. Power-up clear ensures all outputs initialize to OFF state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS(BR) | 40 V - Maximum allowable drain-to-source voltage before breakdown; enables use with 24 V industrial rails and 36 V transient-tolerant LED strings. |
| IO Continuous | 100 mA per channel - Sustained sink current capability per output; supports standard LED indicators and small solenoid drivers without external heatsinking. |
| rDS(on) | 5 Ω typical @ VCC = 5 V, TC = 25°C - Low conduction loss per channel; limits power dissipation to ≤50 mW per active output at 100 mA. |
| Thermal Shutdown | 160°C trigger with 10–30°C hysteresis - Self-protecting behavior under overcurrent or ambient overheating; prevents latch-up or permanent damage. |
| I²C Clock Frequency | Up to 400 kHz - Enables fast configuration updates in real-time systems; compatible with standard-mode I²C controllers without timing margin concerns. |
| ESD Protection | 3000 V HBM on drain outputs - Robust handling during board assembly and field service; eliminates need for external TVS diodes in many LED driver applications. |
| Operating Temperature | −40°C to +125°C case temperature - Qualified for under-hood automotive, factory automation, and outdoor industrial enclosures. |
Pinout & Package
TPIC2810DR is housed in a 16-pin SOIC (D package), 1.27 mm pitch, RoHS-compliant, with moisture sensitivity level (MSL) 1 and peak reflow rating of 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Logic supply input | 3.0–5.5 V nominal supply; powers internal logic, I²C interface, and gate drivers; decoupling capacitor required near pin. |
| SDA (Pin 2) | I²C bidirectional data line | Open-drain, requires external pull-up; handles read/write commands, subaddress decoding (11H/22H/44H), and data transfer. |
| DRAIN0–DRAIN7 (Pins 3–6, 11–14) | DMOS output drains | Eight independent low-side switches; each sinks current to GND when corresponding output register bit = HIGH; rated 40 V / 100 mA continuous. |
| A0–A2 (Pins 9–10, 7) | I²C slave address inputs | Three binary address bits; combine with fixed group ID (1100) to support up to eight uniquely addressable devices on same I²C bus. |
| G (Pin 8) | Global output enable | Active-low enable; when HIGH, all outputs forced OFF regardless of register state; used for system-level emergency shutdown or power sequencing. |
| SCL (Pin 15) | I²C serial clock input | Input-only clock signal; synchronizes all I²C transactions; supports 100 kHz, 400 kHz, and up to 2 MHz (with timing compliance). |
| GND (Pin 16) | Ground reference | Common return path for logic supply, I²C signals, and all DMOS source terminals; must be low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| I²C addressability with A0–A2 pins | Enables daisy-chaining up to eight TPIC2810DRs on one bus without address conflict; simplifies BOM and routing in multi-zone LED control systems. |
| Integrated thermal shutdown | Automatically disables all outputs at 160°C junction temperature with hysteresis; eliminates need for external thermal monitoring circuitry in space-constrained designs. |
| Power-up clear function | Resets shift and output registers to zero on power application; guarantees known OFF-state startup-critical for fail-safe lighting and safety-critical indicators. |
| 210 mA per-output current limiting | Hardware-enforced peak current limit reduces risk of MOSFET failure during short-circuit or inrush events; de-rates smoothly with temperature for predictable behavior. |
| 3000 V HBM ESD on drain outputs | Withstands electrostatic discharge during handling and PCB insertion; meets IEC 61000-4-2 Level 3 requirements without added protection components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side I²C-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL92011DR | Higher voltage (60 V), higher current (200 mA), but no integrated thermal shutdown or power-up clear; uses SPI instead of I²C. | Requires SPI host interface and external thermal management; better suited for high-power LED drivers than status indication. | Select TPL92011DR only if >40 V operation or >100 mA per channel is mandatory and SPI is available. |
| PCA9635PW | I²C-compatible 16-bit LED driver with PWM dimming, but uses bipolar NPN outputs (not DMOS); max 25 mA per channel; no current limiting. | Limited to low-current indicator LEDs; lacks drain voltage rating and overcurrent protection needed for 24 V loads. | Choose PCA9635PW only for ultra-low-power, multi-color RGB LED applications requiring grayscale control-not for industrial load switching. |
Compared with TPL92011DR and PCA9635PW, TPIC2810DR uniquely combines I²C addressability, 40 V/100 mA per channel, integrated thermal shutdown, and guaranteed power-on OFF state-making it optimal for robust, maintenance-free LED and resistive load control in harsh environments.

FAQ
What is the maximum continuous current per channel for TPIC2810DR?
The TPIC2810DR supports 100 mA continuous sink current per channel at TC = 25°C. This rating decreases with rising case temperature-e.g., ~75 mA at TC = 85°C-and is enforced by internal current limiting that activates at 210 mA (pulsed). The value is confirmed in the Recommended Operating Conditions table of SLIS109A.
Does TPIC2810DR support standard-mode I²C communication?
Yes, TPIC2810DR fully supports standard-mode I²C at up to 400 kHz clock frequency, with defined timing parameters including tLOW, tHIGH, tSU:DAT, and tBUF. It also supports fast-mode Plus (up to 2 MHz) with appropriate timing margins, as verified in the Switching Characteristics section of SLIS109A.
How does the thermal shutdown feature operate in TPIC2810DR?
The TPIC2810DR incorporates a die-temperature sensor that triggers automatic shutdown at 160°C, disabling all eight DMOS outputs. Recovery occurs after junction temperature drops below the hysteresis threshold (10–30°C lower), ensuring stable restart. This behavior is documented in the Electrical Characteristics table under TTSD and THYS parameters.
Can TPIC2810DR drive inductive loads such as relays or solenoids?
No-the TPIC2810DR datasheet explicitly states it is "not recommended for switching inductive loads." Its DMOS outputs lack integrated flyback protection, and inductive kickback may exceed the 40 V VDS(BR) rating or damage the internal structure. Use only with resistive or LED loads, as specified in the device description of SLIS109A.
What is the purpose of the G (Output Enable) pin on TPIC2810DR?
The G pin is an active-low global output enable. When driven HIGH, it forces all eight DMOS outputs into high-impedance OFF state-overriding the contents of the output storage register. This enables hardware-level safety interlocks, power sequencing, or emergency stop functions independent of I²C communication. Its behavior is defined in the Terminal Functions table and functional block diagram of SLIS109A.
