SGM892B/SGM893B

Standard CMOS Voltage Detector ICs

GENERAL DESCRIPTION

FEATURES

The SGM892B and SGM893B are low power

consumption voltage detectors with high accuracy

detection. These miniature devices offer tremendous

flexibility with an adjustable threshold that is available

from 1V to 5V with 0.1V increments. These devices are

ideal for use in power-supply sequencing, reset

sequencing, and power-switching applications.

● High Accuracy Detection: ±1% (TYP)

● Low Power Consumption: 0.4μA (TYP) at V_IN= 1V

● Detection Voltage Range: 1V to 5V (0.1V Increments)

● Operating Voltage Range: 1V to 6V

● Detection Voltage Temperature Coefficient:

±40ppm/℃ (TYP)

● Manual-Reset Input (SGM893B Only)

● N-Channel Open-Drain Output

The VOUT pin is an N-channel open-drain output with

active-low reset. An active-low manual-reset input (nMR)

is included in SGM893B.

● -40℃ to +125℃ Operating Temperature Range

● Small Packaging:

SGM892B Available in Green SOT-23-5, SOT-23-3

and UTDFN-1×1-4L Packages

The SGM892B is available in Green UTDFN-1×1-4L,

SOT-23-3 and SOT-23-5 packages. The SGM893B is

available in Green SOT-23-5 and UTDFN-1×1-4L

packages. They are specified over the -40℃ to +125℃

operating temperature range.

OVERSTRESS CAUTION

ABSOLUTE MAXIMUM RATINGS

Stresses beyond those listed in Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to

absolute maximum rating conditions for extended periods

may affect reliability. Functional operation of the device at any

conditions beyond those indicated in the Recommended

Operating Conditions section is not implied.

ESD Susceptibility

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.

SGM892B/SGM893B

Standard CMOS Voltage Detector ICs

DETAILED DESCRIPTION

The SGM892B and SGM893B are supervisory ICs with

ultra-low current and single channel. The voltage

detection range is from 1V to 5V with factory-set 0.1V

increments. When VIN voltage falls below the detection

voltage, V_DET, both devices assert an active low at the

VOUT pin. These devices are designed to immune the

voltage transients of the VIN pin.

VOUT low, even if the VIN voltage is higher than the

factory-set voltage (V_DET+ V_HYS). After nMR returns to a

logic high and the VIN voltage exceeds the threshold

voltage (V_DET+ V_HYS), VOUT is deasserted after the

reset delay time (t_D) elapses. nMR is pulled up to VIN

with an internal 23.5kΩ resistor; this pin can be floating

if nMR is not used. If the driving signal on nMR is lower

than VIN, there will be a leakage current path between

the VIN and nMR pins. To avoid the leakage current, a

logic-level FET can be used, as shown in Figure 6.

The SGM893B remains VOUT asserted for the reset

delay time, t_D, after the VIN voltage rises above the

factory-set voltage (V_DET+ V_HYS).

The SGM893B includes a manual reset input (nMR).

When nMR is pulled low, VOUT is forced low, even if

VIN

23.5kΩ

the VIN voltage is above the factory-set voltage (V_DET

_HYS).

VIN Transient Immunity

The SGM892B and SGM893B devices have built-in

circuit to immune the voltage transients of the VIN pin.

Transient immunity is tightly related to the transient

duration and amplitude. Transient amplitude is

measured from the bottom of the transient to the

detection voltage (V_DET) of the device, as shown in

Figure 5.

Figure 6. Using a Logic-Level FET to Minimize Current Draw

Normal Operation (V_IN> V_{IN_MIN}

)

When the VIN voltage is higher than V_{IN_MIN}, the VOUT

status depends on the VIN voltage relative to V_DETand

the nMR voltage (SGM893B only).

When the voltage on VIN is lower than the power-on

APPLICATION INFORMATION

Ultra-low operating and detection voltages make the

SGM892B and SGM893B devices well-suited for the

single-cell, alkaline-battery systems.

during the SGM892B and SGM893B sampling the input

voltage. If the power source (including trace) shows

high impedance, the additional current during sampling

may trigger a false reset as a result of the apparent

voltage drop at VIN. For this application scenario,

SGMICRO recommends adding a small 0.1μF bypass

capacitor near the SGM892B VIN pin. This bypass

capacitor effectively keeps the average current at

0.4μA.

Figure 7 shows the SGM892B monitoring the single-

cell alkaline battery. When the cell voltage reaches 1V,

which is a typical voltage to stop discharging the

alkaline battery, the SGM892B VOUT pin asserts. The

SGM66099 EN pin is driven low, and places it in a

low-current shutdown state. After SGM66099 is

disabled, the combination of the SGM892B and

SGM66099 devices consumes only 700nA (TYP).

Bidirectional Reset Pins

Some microprocessors or logic devices have

bidirectional reset pins which may operate as input or

output ports depending on their configuration. When

Power Supply Recommendations

≥ 1MHz

The SGM892B/SGM893B input supply voltage range is

between 1V and 6V. It is recommended to use a

low-impedance power supply or a 0.1μF bypass

capacitor to avoid a false reset.

Input Capacitor

The quiescent current is only 0.4μA (TYP). However,

this current rises to approximately 3μA for about 500μs
