Diodes Incorporated DGD0211CWT-7

Overview

DGD0211CWT-7 from Diodes Incorporated is a single-channel, low-side MOSFET/IGBT gate driver IC with 1.9A peak source / 1.8A sink output current, 35ns typical propagation delay, and dual logic inputs (IN/IN*) supporting TTL/CMOS levels down to 3.3V. It operates from 4.5V to 18V supply voltage across –40°C to +125°C and is used in high-frequency switch-mode power supplies for precise gate control of power switches.

For engineers reviewing the DGD0211CWT-7 datasheet, DGD0211CWT-7 pinout, DGD0211CWT-7 application, or DGD0211CWT-7 equivalent, key selection criteria include output drive strength, propagation timing consistency, input logic compatibility, thermal performance in compact TSOT25 packaging, and suitability for non-inverting/inverting control configurations in DC-DC and motor drive stages.

Technical Context

The DGD0211CWT-7 implements a dual-input, single-output gate driver architecture with independent non-inverting (IN) and inverting (IN*) logic inputs that determine output state per truth table: IN=1/IN*=0 → OUT=1; IN=0/IN*=1 → OUT=0. Output stage uses bipolar transistor-based push-pull topology optimized for fast switching.

It features rail-to-rail output swing (VOUT = 0 to VCC), supports capacitive loads up to 1000pF, and maintains stable timing performance across its full operating temperature range. Input bias currents are ≤5µA at VIN=3V, enabling direct interface with low-power MCUs without external level-shifting.

FAQ

What is the maximum capacitive load the DGD0211CWT-7 can drive while maintaining specified rise/fall times?

The DGD0211CWT-7 is characterized for 15ns typical rise/fall times with a 1000pF capacitive load at VCC = 12V. Driving larger loads increases transition times proportionally; for 2000pF, measured tr/tf increase to ~25ns. Layout parasitics and PCB trace inductance also affect real-world performance.

Can the IN and IN* pins be tied together for single-input operation?

Yes - tying IN and IN* together creates a single-input configuration where the output follows IN (non-inverting). However, this disables the inverting function and may increase input capacitance slightly. Ensure the combined input signal meets VIH/VIL thresholds and does not exceed ±0.3V beyond VCC or below COM.

Is the DGD0211CWT-7 qualified for automotive applications?

No - the DGD0211CWT-7 is not AEC-Q100 qualified. Diodes offers automotive-grade variants (e.g., DGD0211Q) with PPAP documentation, IATF 16949 manufacturing, and extended reliability testing. For automotive use, contact Diodes directly for qualified alternatives.

Does the DGD0211CWT-7 require external bootstrap components when used in high-side configurations?

No - the DGD0211CWT-7 is a low-side-only driver and lacks internal charge pump or floating supply capability. It cannot drive high-side N-channel MOSFETs directly. For high-side drive, pair it with a dedicated high-side driver (e.g., DGD0506) or use a P-channel MOSFET with low-side control.
