TS3002 A 1V/1A Easy-to-Use Silicon Oscillator/Timer FEATURES DESCRIPTION Ultra Low Supply Current: 1A at 25kHz The TS3002 is the industrys first and only single- Supply Voltage Operation: 0.9V to 1.8V supply CMOS oscillator fully specified to operate at Programmable Frequency Range: 1V while consuming a 1A supply current at an o 5.2kHz FOUT 90kHz (BOOST = GND) output frequency of 25kHz. This oscillator is compact, o 5.2kHz FOUT 290kHz (BOOST = VDD) easy-to-use, and versatile. Optimized for ultra-long life, battery-powered applications, the TS3002 is the FOUT Period Drift: 0.044%/C PWMOUT Duty Cycle Range: 12% to 90% first oscillator in the NanoWatt Analog high- performance analog integrated circuits portfolio. The Single Resistor and Capacitor Set Output Frequency TS3002 can operate from single-supply voltages from 0.9V to 1.8V. Output Driver Resistance: 160 Requiring only a resistor and a capacitor to set the output frequency, the TS3002 represents a 66% reduction in pcb area and a factor-of-10 reduction in power consumption over other CMOS-based APPLICATIONS integrated circuit oscillators. When compared against industry-standard 555-timer-based products, the Portable and Battery-Powered Equipment TS3002 offers up to 93% reduction in pcb area and Low-Parts-Count Nanopower Oscillator four orders of magnitude lower power consumption. Compact Nanopower Replacement for Crystal and Ceramic Oscillators The TS3002 is fully specified over the -40C to +85C Nanopower Pulse-width Modulation Control temperature range and is available in a low-profile, 8- Nanopower Pulse-position Modulation Control pin 2x2mm TDFN package with an exposed back- Nanopower Clock Generation side paddle.
