Torex Releases Voltage Detectors With 0.7V Voltage Drive & Release Delay Circuit in 0.9 x 1.2mm Package

Torex Semiconductor Ltd. has developed the XC6119 Series of voltage detectors with an internal release delay circuit in a small package. The XC6119 series has been incorporated in the new USPN-4 package (0.9 x 1.2 x 0.4mm) to achieve a size reduction of about 74% over the previous SSOT-24 package (2.1 x 2.0 x h1.1mm).

Using a CMOS process, drive from a low voltage of 0.7V is possible, with a voltage detection range of 0.8 to 5.0V (0.1V increments). A delay circuit is incorporated and a capacitor can be connected to the delay capacitance pin, allowing any release delay to be set. There are two types of output circuits, a CMOS output and an N-ch open drain output.

This series is well suited for use in the power-on reset of microcomputer systems, in battery voltage monitoring circuits, in backup power switching circuits, and other applications.

Among the XC6119 series features: low 0.7V voltage drive is possible; internal delay circuit – release delay time can be adjusted with an external capacitor; low quiescent current of 0.5A typical (detection state, VDF=1.0V, VIN=0.9V) and 0.9A typical (release state, VDF=1.0V, VIN=1.1V); and a small 0.9 x 1.2mm package.
