Modern Core City Agent Line -analog semiconductor,Deliven to provide high -quality chips with excellent domestic simulation and digital model hybrid chip designerShanghai -Ebit Semiconductor Technology Co., Ltd.(The following is called an analog semiconductor or analog), and the launchReinforced PWM suppression current current detection amplifier CSA24X series, To detect the voltage drop at both ends of the distributed resistor within the range of-6V to 80V independent of -6V to 80V independent of the power supply voltage.The CSA24X series products are suitable for motor drive, energy storage, vehicle charger (OBC), electronic assistance steering (EPS), power module and other industrial and automotive applications.Phase lines perform high -precision sampling to help the system achieve accurate current control.
Relying on the PWM suppression module independently developed by analog semiconductor, the CSA24X series current detection amplifier has an excellent enhanced PWM inhibitory function. Under the condition of high -consensus modulus, the current signal can be effectively collected and can be faster to 3V/NS.The co -mode jump signal of the rise/decrease edge is effectively suppressed, so that the establishment of the output signal is less than1.2us Within, this indicator has greatly improved compared to 2US of similar products.Second, the CSA24X seriesThe range of co-mode voltage is -6V ~ 80V, It enables it to work within a lower co -mode voltage range, especially in the application of perceptual load.
CSA24xThe series device uses a zero -temperature drift architecture, which has a low offset, so the maximum pressure on the downtale can be reduced to 10mv (full range) for current detection.In addition, the CSA24X series has better DC performance. Its maximum VOS voltage is ± 15UV, Zero drift ± 0.25UV/℃，Gain error 0.1% DC indicators can help customers achieve more accurate current measurement.
CSA24x Series products are suitable formotor driven、Energy storage、Car charger (OBC)、Electronic help steering (EPS)、Power moduleFor high -side or low -side current sampling in industrial and automotive applications, these systems often need to perform high -precision samples to the bus and phase lines to achieve accurate current control.The CSA24X series products can be applied to the high -co -modular current measurement of the system within all 60V.Realize the entire ring control.
CSA24x The series currently includes two versions: CSA241 and CSA240.450kHz, Able to capture high -speed current transformations more quickly; CSA241 is a low -power version, static power consumption reaches0.8mAIt is suitable for battery supply occasions with high power consumption requirements.
CSA24x The launch of a series of current detection amplifiers enriches the product roadmap of analog semiconductor current exile.The current sampling scheme, with an analog motor driver, digital model converter, high -precision amplifier and other products, can provide customers with a complete overall solution, thereby practicing the analogy of the semiconductor.High -quality chip platform supplierConcept and positioning
