Applications
TC428CPA is used in DC-DC converter gate drive stages, synchronous rectifier circuits, and H-bridge motor drivers where a robust 1.5 A peak current is needed to rapidly charge and discharge MOSFET gates operating from a 4.5 V to 18 V rail. It also suits flyback converter primary-side drivers and industrial solenoid control circuits that require dual-channel high-side drive capability from a simple through-hole component.

Frequently Asked Questions
What peak gate drive current does TC428CPA deliver, and how does that affect MOSFET switching speed?
TC428CPA provides 1.5 A peak source and sink current per channel, enabling fast charging and discharging of MOSFET gate capacitances. For a typical power MOSFET with 20 nC total gate charge, TC428CPA can drive a full gate transition in under 15 ns, reducing switching losses in DC-DC converters and motor drive inverters operating at frequencies up to hundreds of kilohertz.
What supply voltage range does TC428CPA support, and is it compatible with both 5 V logic and 12 V gate drive circuits?
TC428CPA operates from a 4.5 V to 18 V supply, making it directly compatible with 5 V logic-level systems as well as 12 V or 15 V gate drive rails commonly used in IGBT and power MOSFET applications. This broad range eliminates the need for a separate gate drive bias supply in many half-bridge and full-bridge converter designs.
Can TC428CPA drive the high-side switch in a half-bridge topology, and what are its architectural limitations?
Yes, TC428CPA includes high-side driver capability, but it uses a buffer/inverter-based architecture without a built-in bootstrap circuit. Designers implementing high-side switching above the supply rail typically need an external bootstrap diode and capacitor network, or a separate isolated gate drive transformer, to maintain proper gate drive voltage during continuous high-side on-time in half-bridge and full-bridge circuits.
For a power converter prototype, why might an engineer select TC428CPA in PDIP-8 over an equivalent SMT gate driver?
TC428CPA's 8-pin PDIP through-hole package plugs directly into a breadboard or evaluation socket, allowing rapid gate drive circuit iteration without soldering or PCB fabrication. With a 1.5 A drive capability and 4.5 V to 18 V supply range in a socketed DIP-8 footprint, it shortens the prototype cycle for switching power supplies and motor control evaluation boards significantly.
