The SGM865 is a quad voltage monitoring IC designed for supervising multiple power rails in various applications. Each monitored rail features two input pins, VHx and VLx (x = 1, 2, 3, 4), enabling simultaneous detection of over-voltage (OV) and under-voltage (UV) conditions. A shared active-low output pin, nUV/nOV, indicates the status of all monitored rails.
The SGM865 provides a 1V buffered reference output (REF), which can be used as an offset when detecting negative voltages. Additionally, the three-state SEL pin allows configuration of the polarity for VH3/VL3 and VH4/VL4, supporting both positive and negative supply monitoring.
The device integrates an internal shunt regulator, allowing it to operate in high-voltage systems. To protect the VCC pin, a resistor must be added between the main supply rail and VCC, limiting current flow to no more than 10mA. If the supply voltage exceeds 5.5V, the internal shunt regulator will automatically regulate the VCC voltage.
The SGM865 offers two models. The SGM865A/C latches the nOV pin under OV condition by pulling down the nLATCH pin and can be cleared by toggling the nLATCH pin. The SGM865B/D can pull high the nOV and nUV pins with the DIS pin no matter what the monitored signal voltage is.
The SGM865 is available in Green SSOP-16 and TQFN-3×3-16L packages. It operates over the junction temperature range of -40℃ to +125℃.
