GENERAL DEscriptION

The SGM895/SGM896/SGM897/SGM898/SGM899 are ultra-small, low-power and high-accuracy micro-processor supervisory circuits with adjustable se capability. Since the high-impedance detection input pin (IN) with a 0.5V threshold voltage is separated from the power supply, these devices offer tremendous flexibility with an adjustable threshold using an external resistive divider. Moreover, the delay time can be adjusted by an external capacitor connected to the CDELAY pin. These devices are ideal for power-supply se, reset se and power-switching applications.

When the input voltage at IN (VIN) exceeds the VTH threshold voltage (0.5V, TYP) and the enable input is asserted (ENABLE = high or nENABLE = low), the output asserts (OUT = high or nOUT = low). When VIN falls below VTH - VHYST (0.495V, TYP) or when the enable input is deasserted (ENABLE = low or nENABLE = high), the output deasserts (OUT = low or nOUT = high). All devices provide a capacitor-adjustable input delay time (tDELAY) from when VIN exceeds VTH to when the output asserts. The SGM89_A provide the same capacitor-adjustable delay time from when the enable is asserted to when the output asserts, whereas the SGM89_P provide a 350ns (TYP) propagation delay time from when the enable is asserted to when the output asserts.

The SGM895 provides an active-high enable input and an active-high push-pull output. The SGM896 provides an active-low enable input and an active-low push-pull output. The SGM897 provides an active-high enable input and an active-high open-drain output. The SGM898 provides an active-low enable input and an active-low open-drain output. Finally, the SGM899 provides an active-low enable with an active-high push-pull output.

All devices are available in ultra-small Green UTDFN-1.45×1-6AL and TSOT-23-6 packages.
