FEATURES Ultra Low Supply Current: 1.35 μA at 49Hz Supply Voltage Operation: 1.55V to 5.25V Single Resistor Sets FOUT at 50% Duty Cycle 3-pin User-Programmable FOUT Period: 1.7m s ≤ t FOUT ≤ 33hrs FOUT Period Accuracy: 3% FOUT Period Drift: 0.02%/ºC Single Resistor Sets Output Frequency Separate PWM Control and Buffered Output FOUT/PWMOUT Output Driver Resistance: 160Ω 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 DESCRIPTION The TS3005 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 1.5 μA(max) supply current. Requiring only a resistor to set the base output frequency (or output period) at 49Hz (or 20.5ms) with a 50% duty cycle, the TS3005 timer/oscillator is compact, easy-to-use, and versatile. Optimized for ultra-long life, low frequency, battery-powered/portable applications, the TS3005 joins the TS3001, TS3002, TS3003, TS3004, and TS3006 in Touchstone’s CMOS timer family in its “NanoWatt Analog™” series of high-performance analog integrated circuits. The TS3005 output period can be user-adjusted from 1.7ms to 33hrs without additional components. In addition, the TS3005 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 TS3005 offers up to 84% reduction in pcb area and over three orders of magnitude lower power consumption. The TS3005 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. A 1.55V to 5.25V, 1.35µA, 1.7ms to 33hrs Silicon Timer TYPICAL APPLICATION CIRCUIT TS3005, 5 Weeks and 5 Days Counter Circuit The Touchstone Semiconductor logo and “NanoWatt Analog” are registered trademarks of Touchstone Semiconductor, Incorporated. |
