For new designs, we. Floating channel designed for bootstrap operation. Tolerant to negative transient voltage. Matched propagation delay for both channels. Micropower supply startup current of ? Low side output in phase with R T. The IR is a high voltage, high speed, self-os. The output drivers feature a high.

Refer to Lead Assignment diagram for correct pin configuration. Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur.


The Thermal Resistance and Power Dissipation ratings are measured. High Side Floating Supply Voltage. High Side Floating Output Voltage. Low Side Output Voltage. Supply Current Note 1. R T Output Current. Allowable Offset Supply Voltage Transient. Thermal Resistance, Junction to Ambient. Lead Temperature Soldering, 10 seconds. For proper operation the device should be used within the. The V S offset rating is tested with all supplies biased at 15V differential. Because of the IR’s application specificity toward off-line supply datashewt, this IC contains a zener clamp.
