TM

FSB50250UTD

Features

high voltage integrated circuit (HVIC)

• 3 divided negative dc-link terminals for inverter current sens-

ing applications

• HVIC for gate driving and undervoltage protection

• 3/5V CMOS/TTL compatible, active-high interface

• Optimized for low electromagnetic interference

• Isolation voltage rating of 1500Vrms for 1min.

• Embedded bootstrap diode in the package

General Description

FRFET technology as a compact inverter solution for small

power motor drive applications such as fan motors and water

suppliers. It is composed of 6 fast-recovery MOSFET (FRFET),

and

3

half-bridge

HVICs

for

FRFET

gate

driving.

FSB50250UTD provides low electromagnetic interference (EMI)

characteristics with optimized switching speed. Moreover, since

it employs FRFET as a power switch, it has much better

ruggedness and larger safe operation area (SOA) than that of

an IGBT-based power module or one-chip solution. The

package is optimized for the thermal performance and

compactness for the use in the built-in motor application and

any other application where the assembly space is concerned.

FSB50250UTD is the most solution for the compact inverter

providing the energy efficiency, compactness, and low

electromagnetic interference.
