High speed Driver with bootstrapping for
dual Power MOSFETs
TDA21102
Features
P-DSO-8-7 ^P-DSO-14-3
• Fast rise and fall times for frequencies up to 2 MHz
• Capable of sinking more than 4 A peak current for lowest switching losses
• Charges the High Side and Low Side MOSFET´s gate to 6..12 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
• High voltage rating on Phase node
• Supports shut-down mode for very low quiescent current through three-state input
• Compatible to standard PWM controller ICs (Intersil, Analog Devices)
• Floating High Side MOSFET drive
• Ideal for multi-phase Desktop CPU supplies on motherboards and VRM´s
