Overview
The TS3001ITD822T is a single-supply CMOS oscillator from Silicon Labs, designed for ultra-low power applications. It operates within a supply voltage range of 0.9V to 1.8V and consumes only 1µA at an output frequency of 25kHz. The device features a programmable frequency range from 5.2kHz to 90kHz, set by a single external resistor. It provides two outputs: FOUT, a fixed duty cycle square wave, and PWMOUT, a pulse-width modulated signal with a duty cycle range of 12% to 90%. The component is housed in an 8-pin TDFN package measuring 2mm x 2mm.
Feature Summary
- Ultra-low supply current of 1µA at 25kHz operation
- Single-resistor programmable frequency range from 5.2kHz to 90kHz
- Dual outputs: Fixed duty cycle (FOUT) and adjustable PWM (PWMOUT)
- Operates on a single supply voltage between 0.9V and 1.8V
Applications
- Portable and battery-powered equipment
- Low-parts-count nanopower oscillators
- Compact replacement for crystal and ceramic oscillators
- Nanopower pulse-width modulation control
- Nanopower clock generation
Procurement Notes
Verify the specific ordering suffix 'T' for tape and reel packaging containing 3000 units. Confirm lead-free compliance as standard for this product line. Ensure the design accommodates the 8-pin TDFN footprint and exposed paddle grounding requirements specified in the datasheet.
Selection Notes
Select the TS3001 when PCB area reduction and minimal power consumption are critical compared to traditional 555-timer based solutions. Use the RSET pin to program the desired frequency; a 4.32MΩ resistor yields approximately 25kHz. Consider the CNTRL pin if PWM functionality is required, noting that enabling it increases supply current.
Part Context
The TS3001 belongs to Silicon Labs' NanoWatt Analog portfolio, optimized for long-life battery applications. It serves as a low-power alternative to discrete oscillator circuits. The ITD822 designation identifies the industrial temperature grade (-40°C to +85°C) and the specific 8-pin TDFN package configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation.
