SGM890B/SGM891B

Voltage Detector with Separated Sense Pin

and Delay Capacitor Pin

GENERAL DESCRIPTION

FEATURES

The SGM890B and SGM891B are low-power and

high-accuracy voltage detectors. The adjustable

threshold range is 0.8V to 5V with increments of 0.1V,

which greatly provides application flexibility.

● Operating Voltage Range: 1V to 6V

● High Accuracy Detection: ±1% (TYP)

● Low Power Consumption: 0.3μA (TYP) at V_IN= 1V

● Detection Voltage Range: 0.8V to 5V (0.1V Increments)

● Detection Voltage Temperature Coefficient:

±40ppm/℃ (TYP)

Since the sense pin (VSEN) of the devices is separate

from the power supply pin, it can monitor other power

supplies. And when the monitored power supply

voltage drops to 0V, the device can also maintain the

detection state.

● Adjustable Release Delay Time (SGM890B Only)

● Sense Pin Separates from Power Supply

● N-Channel Open-Drain Output

● -40℃ to +125℃ Operating Temperature Range

● Available in a Green SOT-23-5 Package

In addition, the C_Dpin of SGM890B has an external

capacitor connected to GND, which can adjust the

release delay time. Consequently delay time can be set

to more than 1s when the delay capacitor (C_D) is 1μF.

These devices are very suitable for applications in

power sequencing, reset sequencing and power

switching.

ESD SENSITIVITY CAUTION

This integrated circuit can be damaged if ESD protections are

not considered carefully. SGMICRO recommends that all

integrated circuits be handled with appropriate precautions.

Failureto observe proper handlingand installation procedures

can cause damage. ESD damage can range from subtle

performance degradation tocomplete device failure. Precision

integrated circuits may be more susceptible to damage

because even small parametric changes could cause the

device not to meet the published specifications.
