TP2021 - SC70, 1.8V, Nano-power Comparators with Voltage Reference

 

典型应用

 

The TP202x in Low-Side Current Sensing 

 

产品概述

 

The TP2021 has a push-pull output stage with loads up to 25mA. The TP2025 has an open-drain output stage that makes it suitable for mixed-voltage system design. Both feature an on-chip 1.248V ±1.4% reference and draw an ultra-low supply current of only 440nA (max). The TP202x incorporate 3PEAK’s proprietary and patented design techniques to achieve the best world-class performance among all nano-power comparators. Both have 13μs fast response time under 1.8V to 5.5V supply. The internal input hysteresis eliminates output switching due to internal input noise voltage, reducing current draw. They have input common-mode range 200mV beyond the supply rails, and operate down to +1.8V. The integrated 1.248V voltage reference offers low 120ppm/°C drift, is stable with up to 10nF capacitive load, and can provide up to 25mA of output current. These features make the TP202x ideal for all 2-Cell Battery Monitoring/Management. 

 

The TP202x is available in the tiny SC70/SOT23 package for space-conservative designs. Both versions are specified for the temperature range of –40°C to +85°C.
