CURRENT MANUFACTURER OFFERS - HCPL-788J Isolation amplifier with short circuit and overload detection

HCPL-788J Isolation amplifier with short circuit and overload detection – evaluation board Description The HCPL-788J evaluation board allows a power-inverter designer to evaluate the current-monitoring, short-circuit fault detection and high common-mode transient rejection capability of the HCPL-788J analog isolation amplifier. The HCPL-788J, designed for current-sensing applications, may also be used for general voltage sensing. The HCPL-788J incorporates a microcontroller-compatible analog output and short-circuit fault indication as well as other features into a small 300-mil-wide surface-mount package, resulting in greatly simplified current-sense designs. A reference voltage input, VREF2 , may be connected directly to (and driven from) the A/D converter reference voltage. With this connection the full-scale output of the HCPL–788J matches the full-scale input of the A/D for seamless matching to the A/D. Also, the HCPL-788J has an ABSVAL output which can be tied together with ABSVAL of other devices to provide a maximum amplitude signal which can be used to easily generate an over-current signal. The HCPL–788J is immune to common-mode voltage transients as high as 1.5kV and as fast as 15kV/μs. Want to apply for this board?
