SY24631 Datasheet | Silergy

36V High-Speed Zero-Drift Voltage Output Current-Shunt Monitor with High-Speed Overcurrent parator General Description The SY24631 includes a high mon-mode, currentsensing amplifier, as well as a high-speed parator that can be configured to detect over-current conditions. The Current Sense Amplifier is used to accurately measure a small voltage developed across a shunt resistor and provide a proportional analog value at its output. The built-in parator measures the voltage developed at the output of the Current Sense Amplifier and pares that voltage with an externally configured threshold. When the voltage at the Amplifier output is higher than the threshold, its open-drain output will be driven low, effectively enabling fast over-current detection in a system. A single external resistor can be used to configure the over-current threshold. This current-shunt monitor can measure differential voltage signals on mon-mode voltages that can vary from 0V up to 36V, independent of the supply voltage. The open-drain Alert Output can be configured to operate in either transparent mode or latched mode. The device alert response time is under 0.75μs, which allows for quick detection of over-current events. The SY24631 operates from a single 2.7V to 5.5V supply, drawing a maximum supply current of 400μA.The device is specified over the extended operating temperature range (-40°C to +125°C), and is available in an 8-pin MSOP package.
