Telefunken TF21814-TUH High-Side / Low-Side Gate Driver SOP-14
Enhance the performance of your PSU with the Telefunken TF21814-TUH High-Side / Low-Side Gate Drive IC. Designed to drive N-channel MOSFETs and IGBTs in a half-bridge configuration — ideal for power supply applications. High-voltage process allows the high side to switch up to 600V using bootstrap operation.
Equipped with logic inputs compatible with standard TTL and CMOS levels — easy interfacing with controlling devices. High pulse current buffers minimize driver cross-conduction, ensuring optimal performance under continuous switching duty. Operating range -40°C to +125°C for industrial environments. SOP-14 package provides PCB versatility.
Typical Use in PSU Repair
- Half-bridge gate driver replacement — restoring primary-side MOSFET / IGBT drive.
- LLC resonant PSU repair — gate driver for resonant converter switching.
- Industrial SMPS repair — server, telecom, industrial high-voltage PSU.
- Production refurbishment — bulk gate driver stock for PSU rebuild lines.

FAQ — TF21814-TUH Gate Driver
Q: How does it compare to IR2110?
A: Both are 600V high-side / low-side gate drivers. TF21814-TUH is the Telefunken variant. Pin-compatible substitutions possible but verify each pin function against datasheet.
Q: Bootstrap capacitor — what value?
A: Typical 0.1-1 µF ceramic capacitor between VB and VS pins. Verify against your specific PSU schematic for value.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com with your volume.
