Page 1 of 13 DS-CoreControl-TDA21103 Contents: CoreControl TM Page 2 of 13 DS-CoreControl-TDA21103 High speed Driver with bootstrapping for dual Power MOSFETs Features : P-DSOP-14 • Fast rise and fall times for frequencies up to 1 MHz • Changes the High Side and Low Side gate to V according to PVCC setting. • Adjustable High Side and Low Side MOSFET gate drive voltage via PVCC pin for optimizing ON losses and gate drive losses • Integrates the bootstrap diode for reducing the part count • Prevents from cross-conducting by adaptive gate drive control • Supports shut-down mode for low quiescent current through three-state input • Compatible to standard PWM controller ICs Intersil, Analog Devices • Floating High Side MOSFET drive • Power-On Overvoltage Protection • Ideal for multi-phase Desktop CPU supplies on motherboards and Application : • Voltage Regulator Modules • Low Output Voltage High Output Current DC-DC Converters Type Package Marking TDA21103 P-DSOP-14 21103 Ordering Code Q67042-S4252 Pinout Drawing and Description : CoreControl TM Page 3 of 13 DS-CoreControl-TDA21103 The dual high speed driver is designed to drive a wide range of N-Channel low side and N-Channel high side MOSFETs with varying gate charges. It has a small propagation delay from input to output, short rise and fall times and the same pin configuration as the HIP6602B. 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 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 but also in motor drive and half bridge class-D amplifier type applications.
