Isolated Half-Bridge Gate Driver with Integrated Isolated High-Side Supply Data Sheet ADuM6132 FEATURES GENERAL DESCRIPTION iso Power integrated isolated high-side supply
The ADuM61321 is an isolated half-bridge gate driver that
275 mW isolated dc-to-dc converter
employs the Analog Devices, Inc., iCoupler® technology to
200 mA output sink current, 200 mA output source current
provide an isolated high-side driver with an integrated 275 mW
High common-mode transient immunity: >50 kV/µs
high-side supply. This supply, provided by an internal isolated
Wide-body 16-lead SOIC package
dc-to-dc converter, powers not only the ADuM6132 high-side

output but also any external buffer circuitry that is commonly

used with the ADuM6132. This functionality eliminates the
3750 V rms for 1 minute per UL 1577
cost, space, and performance issues associated with external

supply configurations such as a bootstrap circuit.
CSA/IEC 60950-1, 400 V rms
The architecture of the ADuM6132 isolates the high-side

channel and the high-side power from the control and low-

side interface circuitry. Care has been taken to ensure close
VIORM = 560 V peak
matching between the high-side and low-side driver timing characteristics to reduce the need for a dead time margin.
APPLICATIONS
In comparison to gate drivers that employ high voltage level
MOSFET/IGBT gate drivers
translation methodologies, the ADuM6132 offers the benefit

of true, galvanic isolation. The differential voltage between

high-side and low-side channels can be as high as 800 V with

good insulation lifetime (see Table 12). isoPower® uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards. Refer to the AN-0971 Application Note for information about board layout considerations.
