Texas Instruments TPIC2202KC

Overview

TPIC2202KC from Texas Instruments is a dual-channel monolithic N-channel enhancement-mode DMOS power transistor array in KC package, configured as two independent open-drain switches with 60 V V_DS, 7.5 A continuous drain current per channel, and 0.09 Ω typical r_DS(on) at V_GS = 15 V - used for high-current DC motor control and solenoid driving in industrial PLC output modules.

For engineers reviewing the TPIC2202KC datasheet, TPIC2202KC pinout, TPIC2202KC application, or TPIC2202KC equivalent, key selection criteria include avalanche energy rating (120 mJ), junction-to-case thermal resistance (2.4 °C/W), source-drain diode recovery characteristics (200 ns trr), and gate charge profile (13.6 nC total) for robust switching in inductive load environments.

Technical Context

The TPIC2202KC integrates two discrete DMOS transistors in a single KC package with electrically common source terminal and isolated gate/drain terminals. Each channel operates independently with full 60 V breakdown voltage and supports pulsed currents up to 15 A under 10 ms/6% duty cycle conditions.

Its internal source-drain body diode enables freewheeling in inductive loads without external catch diodes, while avalanche-rated operation allows safe energy absorption during inductive turn-off transients - critical for relay and solenoid drive where V_DS overshoot exceeds supply rail.

FAQ

What is the maximum continuous drain current per channel for the TPIC2202KC?

The TPIC2202KC supports 7.5 A continuous drain current per channel when operated within its thermal limits - specifically at case temperature ≤75°C with appropriate heatsinking. At higher case temperatures, it must be derated linearly at 0.42 W/°C, and the 7.5 A rating assumes V_GS ≥15 V and proper PCB copper area or bolt-down heatsink to maintain R_θJC = 2.4 °C/W. The TPIC2202KC datasheet confirms this value under "Continuous drain current, each output" in Absolute Maximum Ratings.

Does the TPIC2202KC have built-in avalanche protection, and how is it specified?

Yes, the TPIC2202KC is explicitly rated for single-pulse avalanche energy of 120 mJ, measured under standardized test conditions (IAS = 7.5 A, V(BR)DSX = 60 V, tav defined per Figure 4). This rating allows the TPIC2202KC to safely absorb inductive turn-off energy without external clamping components - a key differentiator for relay and solenoid driving. The TPIC2202KC's avalanche capability is validated in the Absolute Maximum Ratings table and supported by Figure 4 test circuit details.

Can the TPIC2202KC be driven directly by a 5-V microcontroller GPIO pin?

No - the TPIC2202KC gate threshold voltage (1.2–2.4 V) allows turn-on with 5 V, but its total gate charge (13.6 nC) and recommended V_GS of 15 V for low r_DS(on) require active gate driving. A 5 V GPIO cannot reliably achieve full enhancement or fast switching; a dedicated gate driver (e.g., UCC27531) or level-shifting buffer is required to deliver ≥100 mA peak current and 15 V swing. The TPIC2202KC's gate characteristics are detailed in the Electrical Characteristics table under Q_g, Q_gs, and V_TGS.

What is the role of the metal tab on the TPIC2202KC KC package?

The metal tab on the TPIC2202KC KC package is electrically connected to the SOURCE terminal (Pin 3) and serves as the primary thermal conduction path from die to heatsink. It must be insulated from chassis ground if the source node is not at system ground potential - typically using a mica or polymer insulator with thermal grease. This design enables >30 W total power dissipation when mounted to a properly sized heatsink, as confirmed by the R_θJC = 2.4 °C/W specification in the Thermal Resistance section of the TPIC2202KC datasheet.

How does the TPIC2202KC handle reverse recovery in inductive loads?

The TPIC2202KC incorporates an integrated source-drain body diode with 200 ns reverse recovery time (trr) at ID = 7.5 A, VDS = 48 V, and di/dt = 100 A/µs - enabling controlled freewheeling without external diodes. Its Q_RR is 1.5 µC, limiting stored charge-related switching loss and EMI. This behavior is characterized in the Source-Drain Diode Characteristics table and Figure 1 waveforms, confirming the TPIC2202KC's suitability for PWM-driven inductive loads like DC motors and solenoids.
