Product details
Overview
TPIC2810DRG4 from Texas Instruments is an 8-channel, low-side, open-drain DMOS power switch IC with I²C interface, designed to drive resistive loads such as LEDs. It delivers 100 mA continuous sink current per channel, features 40 V drain-to-source breakdown voltage, thermal shutdown at 160°C, and operates across −40°C to 125°C case temperature.
For engineers reviewing the TPIC2810DRG4 datasheet, TPIC2810DRG4 pinout, TPIC2810DRG4 application, or TPIC2810DRG4 equivalent, this page provides verified functional context, validated pin roles, confirmed I²C protocol behavior, real-world load-driving capability, and direct alternative part comparisons for LED array control and industrial status indication systems.
Technical Context
The TPIC2810DRG4 integrates an 8-bit serial-in/parallel-out shift register and an 8-bit D-type output storage register, both controlled via a standard I²C bus (SCL/SDA) with group ID 1100b and user-configurable 3-bit slave address (A0–A2). Data transfer requires subaddress validation (11H, 22H, or 44H) before loading or latching.
Each of the eight DMOS outputs is a low-side switch with internal current limiting (210 mA peak at TC = 25°C), thermal shutdown protection, and 3000 V HBM ESD rating on drains. Output enable (G) is active-low and provides global control over all channels' sink-state transparency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS(BR) | 40 V - Maximum drain-to-source voltage before breakdown; enables safe operation with 24 V LED strings or industrial logic-level loads. |
| IO (continuous) | 100 mA per channel - Sustained sink current capability per output; supports common LED indicator and small-solenoid drive applications. |
| rDS(on) | 5 Ω typical at VCC = 5 V, TC = 25°C - On-resistance determines power dissipation and voltage drop under load; impacts thermal design at full channel count. |
| I²C clock frequency | Up to 2 MHz - Supports high-speed configuration updates without bus contention; compatible with fast microcontroller hosts. |
| Thermal shutdown | 160°C junction setpoint with 10–30°C hysteresis - Self-protects against sustained overload or ambient overheating; automatically recovers after cooldown. |
| Operating temperature | −40°C to 125°C case - Qualified for under-hood automotive, industrial PLC, and harsh-environment embedded control use cases. |
| ESD protection | 3000 V HBM on drain pins - Robust handling during board assembly and field service; reduces need for external TVS in many LED driver layouts. |
Pinout & Package
TPIC2810DRG4 is housed in a 16-pin SOIC (D package), 1.27 mm pitch, with exposed pad not present. Pin numbering follows standard top-view orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Logic supply input | 3.0–5.5 V digital core power; must be decoupled locally to suppress I²C switching noise. |
| SDA (Pin 2) | I²C bidirectional data line | Open-drain interface requiring external pull-up; supports multi-master arbitration and ACK/NACK signaling. |
| 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. |
| A2–A0 (Pins 7, 10, 9) | Slave address inputs | Set 3-bit device address (0–7); allow up to eight TPIC2810DRG4 devices on same I²C bus without address conflict. |
| G (Pin 8) | Global output enable | Active-low; disables all outputs simultaneously when high; used for emergency shutdown or power sequencing. |
| GND (Pin 16) | Ground reference | Common return for logic and power paths; must be low-impedance to minimize ground bounce during simultaneous switching. |
| SCL (Pin 15) | I²C clock input | Master-generated timing signal; edge-triggered sampling; requires external pull-up and trace length matching for >400 kHz operation. |
Key Features
| Feature | Design Value |
|---|---|
| I²C-compatible control interface | Supports standard and fast-mode (up to 2 MHz) I²C; eliminates need for parallel GPIO or SPI translation logic in MCU-based systems. |
| Per-output current limiting | 210 mA peak limit at 25°C, derated with temperature; prevents latch-up or thermal runaway during short-circuit or overcurrent events. |
| Power-up clear circuit | Resets shift and output registers to OFF state at VCC ramp-up; ensures known initial condition without external reset sequencing. |
| Thermal shutdown with hysteresis | Shuts down all outputs at 160°C junction temp and re-enables only after cooling by ≥10°C; avoids oscillation near trip point. |
| High-voltage drain tolerance | 40 V VDS rating allows direct connection to 24 V industrial rails or automotive battery-supplied LED arrays without external flyback clamping. |

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 |
|---|---|---|---|
| TPL9201DR | Single-channel, 2 A sink switch with analog dimming; no I²C interface - uses PWM and EN control instead. | Requires MCU GPIO or dedicated PWM generator; lacks multi-device addressing and register-based configuration. | Choose for higher-current single-load applications where I²C scalability is unnecessary and analog dimming is required. |
| PCA9674APW | 8-bit I²C GPIO expander with push-pull outputs (not open-drain); max 25 mA per pin; no current limiting or thermal shutdown. | Cannot drive LEDs or solenoids directly without external transistors; lacks built-in protection features. | Choose only for logic-level signal routing; avoid for power-switching loads unless paired with external DMOS drivers. |
Compared with TPL9201DR and PCA9674APW, the TPIC2810DRG4 uniquely combines scalable I²C control, integrated current limiting, thermal protection, and 100 mA per-channel sink capability in a single 16-pin SOIC - making it optimal for compact, self-protected LED and resistive-load arrays without added support components.

FAQ
What is the maximum continuous current per channel for the TPIC2810DRG4?
The TPIC2810DRG4 supports 100 mA continuous sink current per output channel at TC = 25°C. This rating decreases with rising case temperature due to thermal derating - for example, to approximately 75 mA at TC = 85°C and lower at 125°C - as defined in the datasheet's rDS(on) vs. temperature curves.
Does the TPIC2810DRG4 support true I²C multi-master arbitration?
Yes, the TPIC2810DRG4 implements standard I²C protocol compliance including open-drain SDA/SCL lines, clock stretching support, and ACK/NACK handshaking. Its SDA pin is bidirectional and actively drives low during ACK, enabling full multi-master arbitration on shared buses.
Can the TPIC2810DRG4 safely drive inductive loads like relays or solenoids?
No - the TPIC2810DRG4 is explicitly not recommended for inductive loads per its datasheet. It lacks internal flyback diodes or clamp circuits, and its DMOS outputs are optimized for resistive loads such as LEDs. Driving inductive loads risks voltage overshoot exceeding the 40 V VDS(BR), potentially causing failure.
How does the TPIC2810DRG4 handle power-up initialization?
The TPIC2810DRG4 includes an internal power-up clear (PUC) circuit that resets both the shift register and output storage register to logic LOW upon VCC ramp-up, ensuring all eight outputs start in the OFF (high-impedance sink disabled) state without requiring external reset signals or firmware initialization.
What is the function of the G (Output Enable) pin on the TPIC2810DRG4?
The G pin is an active-low global output enable. When held HIGH, all eight DMOS outputs are forced OFF regardless of register contents. When pulled LOW, the output storage register values become transparent to the drain drivers - meaning register HIGH = sink enabled, register LOW = sink disabled.
