Frequently Asked Questions
What peak drive current does each channel of the TC4426AEPA deliver for MOSFET gate charging?
Each channel of the TC4426AEPA can source and sink up to 1.5A of peak current, which is sufficient to drive MOSFET gates with input capacitances up to several nanofarads in under 50 ns, enabling switching frequencies of several hundred kHz in power converter designs.
Can the TC4426AEPA operate from a 12V rail in an automotive-adjacent industrial application?
Yes, the TC4426AEPA is rated for a supply voltage range of 4.5V to 18V, so a 12V rail is well within specification. The device's temperature range of -40°C to +125°C also makes it suitable for industrial environments with elevated ambient temperatures.
How does the inverting logic of the TC4426AEPA affect its use in half-bridge driver circuits?
In the TC4426AEPA each channel inverts its input, meaning a logic-high input pulls the gate output low and vice versa. For a half-bridge, this means the two complementary gate signals for the high-side and low-side MOSFETs require matching logic inversion in the PWM controller, which adds one signal inversion step but reduces dead-time complexity in certain topologies.
Does the 8-pin PDIP-8 package of the TC4426AEPA support standard IC sockets for field replacement?
Yes. The PDIP-8 package has 8 pins on a standard 2.54 mm pitch, compatible with widely available 8-pin DIP sockets. This makes the TC4426AEPA easy to replace in field-serviceable industrial control boards without soldering, which is useful during maintenance or failure analysis.
