FEATURES Ultra Low Supply Current: 1µA at 25kHz Supply Voltage Operation: 0.9V to 1.8V Programmable Frequency Range: o 5.2kHz ≤ FOUT ≤ 90kHz (BOOST = GND) o 5.2kHz ≤ FOUT ≤ 290kHz (BOOST = VDD) FOUT Period Drift: 0.044%/°C PWMOUT Duty Cycle Range: 12% to 90% Single Resistor and Capacitor Set Output Frequency Output Driver Resistance: 16 0Ω APPLICATIONS Portable and Battery-Powered Equipment Low-Parts-Count Nanopower Oscillator Compact Nanopower Replacement for Crystal and Ceramic Oscillators Nanopower Pulse-width Modulation Control Nanopower Pulse-position Modulation Control Nanopower Clock Generation Nanopower Sequential Timing DESCRIPTION The TS3002 is the industry’s first and only single- supply CMOS oscillator fully specified to operate at 1V while consuming a 1µA supply current at an output frequency of 25kHz. This oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, battery-powered applications, the TS3002 is Touchstone’s first oscillator in the “NanoWatt Analog™” high-performance analog integrated circuits portfolio. The TS3002 can operate from single-supply voltages from 0.9V to 1.8V. 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 integrated circuit oscillators. When compared against industry-standard 555-timer-based products, the TS3002 offers up to 93% reduction in pcb area and four orders of magnitude lower power consumption. The TS3002 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8- pin 2x2mm TDFN package with an exposed back- side paddle.
