It has a small propagation delay from PWM input pin to GATEHS and GATELS, short rise and fall times and the same pin configuration as the ADP3418. In addition it provides several protection features as well as a shut down mode for efficiency reasons. Target application The dual high speed driver is designed to work well in half-bridge type circuits where dual N-Channel MOSFETs are utilized. A circuit designer can fully take advantage of the driver´s capabilities in highefficiency, high-density synchronous DC/DC converters that operate at high switching frequencies, e.g. in multi-phase converters for CPU supplies on motherboards and VRM´s but also in motor drive and half bridge class-D amplifier type applications.

C1 and C2 should be placed at the drain of Q1 and Q2 and the source of Q3 and Q4. 2. C7 should be placed close to the VCC pin and GND pin of TDA21107. 3. 1N4148, C6 and R2 should be placed close to TDA21107. 4. The traces of GATEHS and PHASE should be routed in parallel and the trace width should not be less than 40 mil. 5. The trace width of GATELS should not be less than 40 mil and it should be clsoe to the gate pins of Q3 and Q4. 1 CoreControl TM 2 Title Size A4 Date: File: 3 Page 5 of 12 D CoreControl Driver TDA21107 Number Revision Application Circuit 1,0 09.08.2004 Sheet of C:\UserData\..\TDA21107_Application.SCHDOC Drawn By: Edward Chang 4 DS-CoreControl-TDA21107 Absolute Maximum Ratings At Tj = 25 °C, unless otherwise specified Parameter Symbol Value Unit Min MAX Voltage supplied to ‘VCC’ pin; DC VVCC -0.3 15 Voltage supplied to ‘PWM’ pin VPWM -0.3 7 VBOOT – VPHASE -0.3 15 Voltage supplied to ‘BOOT’ pin referenced to ‘GND’ VBOOT -0.3 30 Voltage rating at ‘PHASE’ pin, VPHASE -4 15 Voltage supplied to GATEHS pin referenced to ‘PHASE VGATEHS VPHASE VBOOT - 0.3 +0.3 -0.3 VVCC Voltage supplied to ‘BOOT’ pin referenced to ‘PHASE’ V Voltage supplied to GATELS pin referenced to ‘GND’ VGATELS +0.3 Junction temperature TJ 0 150 Storage temperature TS -40 150 Lead temperature (Soldering, 10 seconds) 260 ESD Rating; Human Body Model Machine Mode IEC climatic category; DIN EN 60068-1 CoreControl TM °C 2 KV 200 V 55/150/56 Page 6 of 12 DS-CoreControl-TDA21107 Thermal Characteristic Parameter Symbol Values Min.
