TP2150B
DUAL HIGH SIDE AND LOW SIDE MOSFET DRIVER
Technical Information
Revision 1.7 – June 2004
GENERAL DESCRIPTION
The TP2150B is a high speed, dual high side and low side MOSFET driver. The TP2150B level shifts CMOS
or TTL input levels to gate signals for driving high voltage and high current MOSFETs in a dual half bridge or
single full bridge configuration. The built in bootstrap circuitry allows for the high side to drive an N-channel
power MOSFET
.
Applications
Switch mode audio power amplifier
Switch mode power supply
MOSFET driver
Features
Pin Compatible with Tripath TP2350B
Supports wide range of power supplies
Built in switching regulator driver to power the
gate drive circuitry (VN10)
Over-current protection
Over-temperature protection
Benefits
Reduced system cost with smaller/less
expensive power supply and heat sink
Signal fidelity equal to high quality Class-AB
amplifiers when paired with Tripath TC2001
Floating reference high side driver allows for N
channel output power MOSFETs on the high
side.
