Frequently Asked Questions
What peak gate drive current does TC1426CPA deliver, and why does that matter for MOSFET switching speed?
TC1426CPA can source and sink up to 1.5 A peak current per channel. Higher peak gate current charges and discharges the MOSFET gate capacitance faster, reducing transition times and switching losses, which is critical in converters running above 100 kHz.
Over what supply voltage range does TC1426CPA operate to suit different power rail environments?
TC1426CPA operates from 4.5 V to 18 V, covering 5 V logic systems, 12 V automotive or industrial rails, and 15 V gate-drive bootstrap supplies. Both channels share the same supply pin, simplifying PCB layout for half-bridge configurations.
Is the 8-pin DIP package of TC1426CPA compatible with standard IC sockets for rapid prototyping?
Yes. The 8-pin PDIP package fits 0.3-inch DIP sockets and standard breadboards, making TC1426CPA practical for bench prototyping. For production SMT boards, Microchip also offers the TC1426 in an SOIC-8 package that is pin-compatible.
Does TC1426CPA meet RoHS requirements for lead-free manufacturing?
Yes. TC1426CPA carries the Pb-free code and JESD-609 e3 moisture sensitivity rating, confirming it is RoHS-compliant and lead-free soldered. This makes it suitable for consumer, industrial, and automotive designs subject to RoHS and WEEE directives.
