Frequently Asked Questions
How much peak gate current can TC4428ACPA deliver and why does this matter for switching speed?
TC4428ACPA delivers up to 1.5 A peak current per channel for both sourcing and sinking, enabling rapid charge and discharge of MOSFET gate capacitances, which directly reduces switching transition time and lowers switching losses at frequencies above 100 kHz.
Can TC4428ACPA drive MOSFETs from a 12 V gate-drive rail in a DC-DC converter design?
Yes, TC4428ACPA operates from 4.5 V to 18 V supply, making 12 V gate-drive rails fully supported; the 1.5 A drive strength can fully enhance most standard power MOSFETs with gate charge under 100 nC within tens of nanoseconds.
What is the difference between TC4428ACPA and TC4427ACPA, and when should each be selected?
TC4428ACPA provides one non-inverting and one inverting driver channel, while TC4427ACPA provides 2 non-inverting channels; choose TC4428ACPA when complementary gate signals for a push-pull or half-bridge topology are needed from a single 8-pin PDIP package.
Does the Schmitt trigger input of TC4428ACPA improve noise immunity in noisy PWM environments?
Yes, the Schmitt trigger input provides hysteresis of approximately 0.6 V, preventing spurious switching from high-frequency noise on PWM signal lines, which is particularly important in motor-drive and switching-regulator environments where ground bounce and inductive noise are common.
What through-hole package options and lead time should buyers plan for with TC4428ACPA?
TC4428ACPA is available in an 8-pin PDIP-8 through-hole package with 2.54 mm pin pitch; factory lead time is approximately 11 weeks, so procurement teams should plan buffer stock or place blanket orders for uninterrupted production of power-conversion boards.
