What are the key features of TC1426COA?
- Dual-channel buffer/inverter-based MOSFET gate driver with 2 independent drive functions in a single 8-pin SOIC
- Standard logic-level input threshold compatibility for direct connection to MCU or PWM controller outputs
- Low-side drive topology for N-channel MOSFET switching in DC-DC converters and motor drive half-bridges
- SOIC-8 surface-mount package enabling compact PCB layout with standard SMT reflow assembly
- Pb-free, RoHS-compliant with 6-week factory lead time for flexible supply chain management
What is TC1426COA used for?
TC1426COA is used in DC-DC power converters, motor controllers, and PWM amplifier circuits where a dual-channel gate driver is needed to switch N-channel MOSFETs from logic-level control signals. Its buffer and inverter configuration makes it suitable for half-bridge and push-pull converter topologies requiring complementary drive signals with controlled rise and fall times. The compact SOIC-8 package is commonly used in industrial power supplies, battery management modules, and embedded motor drive boards.

Frequently Asked Questions
How does TC1426COA's dual-channel configuration benefit half-bridge MOSFET drive circuits?
TC1426COA provides 2 independent drive channels in a single SOIC-8 package, allowing one buffer and one inverter output to drive both the high-side and low-side MOSFETs of a half-bridge from a single PWM input signal, simplifying PCB routing and reducing component count compared to using two separate single-channel gate driver ICs.
What input logic level does TC1426COA require, and can it be driven directly from a 3.3 V MCU PWM output?
TC1426COA accepts standard logic-level inputs, so it is compatible with 3.3 V and 5 V PWM signals from microcontroller GPIO outputs. This eliminates the need for level-shifting circuitry between a 3.3 V MCU and the gate driver input, reducing BOM cost and simplifying schematic design for typical motor drive and switching regulator applications.
What are the PCB layout advantages of the SOIC-8 package for TC1426COA in a high-frequency switching supply?
The SOIC-8 package places the 8 driver pins in a compact surface-mount footprint with approximately 3.9 mm x 4.9 mm body dimensions, enabling short trace routing between the driver outputs and MOSFET gates, which minimizes parasitic inductance and reduces gate drive ringing at switching frequencies above 100 kHz in DC-DC converter designs.
When is TC1426COA a suitable alternative to a single-channel gate driver, and what tradeoffs should be considered?
TC1426COA is preferred when 2 independent drive channels are needed without doubling the IC count, such as in synchronous buck converters or push-pull stages requiring both a buffer and an inverter output. The tradeoff is that both channels share the same supply pins and thermal dissipation envelope of the 8-pin SOIC body, so designers must verify the package's maximum power dissipation rating at the intended switching frequency and peak gate charge per cycle.
