New dual voltage supervisor module IN SOT-25

Article Type: New products From: Microelectronics International, Volume 26, Issue 1

Combining the XC6108 with the XC6109 voltage supervisor in one small SOT-25 package, the XCM410 Series (Figure 1) is the newest multi-chip module from Torex Semiconductor and features an ultra-low power consumption of only 1.7 μA. The supervisor IC is ideal for those applications that need to monitor more than one voltage rail with a high degree of accuracy, such as microprocessor re-set circuits, memory battery back-up switch circuits and power failure detection circuits.

The XCM410 operates from a supply voltage within a range of 1.0 to 6.0 V and is a semi-custom product with two voltage sense pins, VSEN and VIN. Two different detect voltages can be selected internally, in 0.1 V increments, from 0.8 to 5.0 V (Channel 1) and 1.1 to 5.0 V (Channel 2).

Torex Semiconductor’s XCM410 ICs feature an N-channel open drain output configuration. Since the sense pin, VSEN, is separated from the power supply, it maintains the sensing status (low-level output) even when the monitored voltage drops to 0 V. Moreover, by connecting dividing resistors to the VSEN pin, the device can detect a higher voltage than its operation voltage.
