SGM862

Dual-Channel, Low-Power,

High-Accuracy Voltage Detector

GENERAL DESCRIPTION

FEATURES

The SGM862 family is a high-accuracy, low-power, and

small size dual-channel voltage detector which can

monitor two power rails respectively.

● Supply Voltage Range: 1.65V to 6.5V

● High-Accuracy Threshold and Hysterisis:

 1.5% at V_DD= 1.65V to 3.3V

 1.7% at V_DD= 1.65V to 6.5V

SENSEx is the input pin which can be programmed with

an external resistor divider. There are four different

hysteresis options of 0.6%, 1%, 5% or 10%.

● Low Quiescent Current: 1.1µA (TYP)

● Four Hysteresis Options: 0.6%, 1%, 5% and 10%

● Open-Drain Output

OUTx is the open-drain corresponding output of SENSEx.

OUTx goes low when the input voltage of SENSEx is

lower than the falling threshold (V_IT-). OUTx goes high

when the input voltage of SENSEx is higher than the

rising threshold (V_IT+). The internal hysteresis of SENSEx

has glitch immunity and ensures stable operation.

● Available in Green UTDFN-1.45×1-6AL and

SOT-23-6 Packages

APPLICATIONS

DSP or Microcontroller

Notebooks and Tablet Computers

Portable and Handheld Devices

Battery-Powered Products

Set-top Boxes

The device has low quiescent current of 1.1µA (TYP),

high accuracy and small size, which is particularly suitable

for system-monitoring of low power and portable

equipment.

Solid-State Drives (SSD)

Building Automation

The SGM862 is available in Green UTDFN-1.45×1-6AL

and SOT-23-6 packages.
