SGM890BxQ
Automotive GradeVoltage Detector with Separated Sense Pin and Delay Capacitor Pin
The SGM890BxQ is a low-power and high-accuracy voltage detector. The adjustable threshold is 1.0V and 3.0V, which greatly provides application flexibility.
Since the sense pin (VSEN) of the device is separated from the power supply pin, it can monitor other power supplies. And when the monitored power supply voltage drops to 0V, the device can also maintain the detection state.
In addition, the CD pin of SGM890BxQ has an external capacitor connected to GND, which can adjust the release delay time. Consequently delay time can be set to more than 1s when the delay capacitor (CD) is 1μF. The device is very suitable for applications in power sequencing, reset sequencing and power switching.
This device is AEC-Q100 qualified (Automotive Electronics Council Standard Q100 Grade 1) and the use of this device is suitable for automotive applications.
The SGM890BxQ is available in a Green SOT-23-5 package. It operates over the -40 ℃ to +125 ℃ temperature range.
