DESCRIPTION

· The TS3003 is a single-supply, second-generation oscillator/timer operating from 1.55V to 5.25V with less than 2.4μA(max) supply current.
· It requires only a resistor to set the base output frequency at 25kHz with a 50% duty cycle.
· Optimized for ultra-long life, low frequency, battery-powered/portable applications.
· Offers a 25% reduction in PCB area and 10x lower power consumption compared to other CMOS-based oscillators/timers.
· Fully specified over the -40°C to +85°C temperature range, available in a 10-pin 3x3 mm TDFN package.

FEATURES

· Ultra Low Supply Current: 1.9μA at 25kHz.
