DESCRIPTION
The TS3003 is a single-supply, second-generation
Touchstone Semi oscillator/timer fully specified to
operate at a supply voltage range of 1.55V to 5.25V
while consuming less than 2.4μA(max) supply
current. Requiring only a resistor to set the base
output frequency (or output period) at 25kHz (or
40µs) with a 50% duty cycle, the TS3003
timer/oscillator is compact, easy-to-use, and versatile.
Optimized for ultra-long life, low frequency,
battery-powered/portable applications,
TS3003 joins
the TS3001, TS3002, TS3004, and TS3006
in
Touchstone’s CMOS timer family in its “NanoWatt
Analog™” series of high-performance analog
integrated circuits.
The TS3003 output frequency can be user-adjusted
from 10kHz to 300kHz with a single resistor. In
addition, the TS3003 represents a 25% reduction in
pcb area and a factor-of-10 lower power consumption
over
other
CMOS-based
integrated
circuit
oscillators/timers. When compared against industry-
standard 555-timer-based products, the TS3003
offers up to 84% reduction in pcb area and over three
orders of magnitude lower power consumption.
The TS3003 is fully specified over the -40°C to +85°C
temperature range and is available in a low-profile,
10-pin 3x3mm TDFN package with an exposed
back-side paddle.
APPLICATIONS
Portable and Battery-Powered Equipment
Low-Parts-Count Nanopower Oscillator
Compact Micropower Replacement for Crystal and
Ceramic Oscillators
Micropower Pulse-width Modulation Control
Micropower Pulse-position Modulation Control
Micropower Clock Generation
Micropower Sequential Timing
