Description
BTD21520 is an isolated dual-channel gate driver with
peak 4-A source current and peak 6-A sink current.It
isolates primary-side from secondary-side by a 5k Vrms
reinforced isolation barrier.
Internal functional isolation between the two secondary-
side output channels allows a operating voltage of
up to 1850 VDC. The driver can be configured as two lowside
drivers, two high-side drivers, or a half-bridge driver
with programmable dead time (DT). Certain models
include disable (DIS) pin. When the DIS pin is set high, it
shuts down both outputs simultaneously. When the DIS
pin is left open or grounded, it allows the device to operIndustrial:
ate normally.
