TLV3011

TLV3012

Nanopower, 1.8V, SOT23

Comparator with Voltage Reference

DESCRIPTION

The TLV3011 is a low-power, open-drain output comparator;

the TLV3012 is a push-pull output comparator. Both feature

an uncommitted on-chip voltage reference. Both have 5µA

(max) quiescent current, input common-mode range 200mV

beyond the supply rails, and single-supply operation from

1.8V to 5.5V. The integrated 1.242V series voltage reference

offers low 100ppm/°C (max) drift, is stable with up to 10nF

capacitive load, and can provide up to 0.5mA (typ) of output

current.

The TLV3011 and TLV3012 are available in the tiny SOT23-6

package for space-conservative designs. It is also available in

the SC70 package for even greater board area savings. Both

versions are specified for the temperature range of –40°C to

+125°C.

APPLICATIONS INFORMATION The TLV3011 is a low-power, open-drain comparator with on-chip 1.242V series reference. The open-drain output allows multiple devices to be driven by a single pull-up resistor to accomplish an OR function, making the TLV3011 useful for logic applications. may be added by connecting a small amount of feedback to the positive input. Figure 2 shows a typical topology used to introduce hysteresis, described by the equation: VHYST = The TLV3012 comparator with on-chip 1.

POWER-ON RESET The reset circuit shown in Figure 4 provides a time delayed release of reset to the MSP430 microcontroller. Operation of the circuit is based on a stabilization time constant of the supply voltage, rather than on a predetermined voltage value. The negative input is a reference voltage created by the internal voltage reference. The positive input is an RC circuit that provides a power-up delay.
