TP2021/TP2025  
SC70, 1.8V, Nano-power Comparators with Voltage Reference  
Features  
Description  
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  
Ultra-Low Supply Current:  
390 nA Comparator with Reference  
system design. Both feature an on-chip 1.248V  
±1.8% 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.  
Internal 1.248V ± 1.8% Reference @ VDD =5V  
Fast Response Time: 13 μs Propagation Delay,  
with 100 mV Overdrive  
Internal Hysteresis for Clean Switching  
Offset Voltage: ± 2.0 mV Maximum  
Offset Voltage Temperature Drift: 0.3 μV/°C  
Input Bias Current: 6 pA Typical  
Input Common-Mode Range Extends 200 mV  
Push-Pull Output with ±25 mA Drive Capability  
Open-Drain Output Version Available: TP2025  
No Phase Reversal for Overdriven Inputs  
Low Supply Voltage: 1.8V to 5.5V  
Green, Space-Saving SC70/SOT23 Package  
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.  
Applications  
Battery Monitoring / Management  
Alarm and Monitoring Circuits  
Threshold Detectors/Discriminators  
Sensing at Ground or Supply Line  
Oscillators and RC Timers
