TS9001 Overview

1.6V Nanopower Comparator with Internal Reference

TS9001
1.6V Nanopower Comparator with Internal Reference
FEATURES
Improved Electrical Performance
over MAX9117-MAX9118
Guaranteed to Operate Down to +1.6V
Ultra-Low Supply Current: 600nA
Internal 1.252V ±1% Reference
Input Voltage Range Extends 200mV Outside-
the-Rails
No Phase Reversal for Overdriven Inputs
Output Stage: Push-pull (TS9001-1)
Open-Drain (TS9001-2)
Crowbar-Current-Free Switching
Internal Hysteresis for Clean Switching
5-pin SC70 Packaging
DESCRIPTION
The nanopower TS9001-1/2 analog comparators
guarantee +1.6V operation, draw very little supply
current, and have robust input stages that can
tolerate input voltages beyond the power supply. Both
products are Touchstone Semiconductor’s first
analog comparator products in its “NanoWatt Analog”
high-performance analog integrated circuits portfolio.
The TS9001-1/2 draw 600nA of supply current and
include an on-board +1.252V±1% reference. These
comparators are also electrically and form-factor
identical to the MAX9117 and the MAX9118 family of
analog comparators. Both comparators offer a 33%
improvement in voltage reference initial accuracy and
the TS9001-1 offers 73% higher output current drive.
The TS9001-1’s push-push output drivers were
designed to drive 5mA loads from one supply rail to
the other supply rail. The TS9001-2’s open-drain
output stage make it easy to incorporate this analog
comparator into systems that operate on different
supply voltages. Both devices are available in an
ultra-small 5-pin SC70 package.
