Single/Dual 4-Amp isolated gate drivers with high transient immunity for high
reliability industrial, military and power applications. SCDs are supported, devices
are tested and shipped from Teledyne’s certified US production facility.
MILPITAS, CA – November 11th, 2021 – Teledyne
e2v HiRel today announced availability of a pair of new isolated gate drivers ideally
suited for driving GaN power parts used in a wide variety of power supply, dc/dc
converter, battery management systems (BMS), Point−of−Load (POL) modules and motor
TDGD27x isolated gate drivers utilize silicon isolation technology, supporting
up to 2.5 kVrms. This technology enables industry leading common-mode transient
immunity (CMTI), tight timing specifications, reduced variation with temperature
and age, better part-to-part matching, and 100% AC/DC testing at −55 °C to
The TDGD271 is a single channel driver with very low jitter, offered in an 8−pin
SOIC package. The TDGD274 dual channel driver can be driven with PWM (pulse width
modulated) inputs and is offered in a 16−pin SOIC package. The TDGD27x family devices
are ideal for a wide range of isolated MOSFET/IGBT and SiC or GaN HEMT gate drive
applications, including driving Teledyne HiRel's TDG family of GaN HEMTs. Their
small size and wide temperature range (−55 to +125 °C) make them unique.
"Many power applications are taking advantage of the reduced size and higher
efficiency made possible by wide band-gap (WBG) semiconductors. However, there was
a lack of supporting functions suitable for the most demanding high reliability
applications," said Mont Taylor, VP of Business Development at Teledyne HiRel. "The
TDGD isolated gate drivers are available with 100% screening and from one diffusion
lot, making them a natural choice for the most demanding systems."
Devices are available for ordering and shipment today from Teledyne e2v HiRel
or an authorized distributor. They are shipped from our DoD Trusted Facility in
