LTC6992IS6-1#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-1#TRPBF is a silicon oscillator and voltage-controlled pulse width modulator (PWM) from the TimerBlox family, manufactured by Analog Devices Inc. It operates on a single supply of 2.25V to 5.5V with a typical supply current of 365µA at 5.5V. The output frequency ranges from 3.81Hz to 1MHz, determined by an external resistor RSET and an internal programmable divider NDIV (1 to 16384). The duty cycle is controlled via a 0V to 1V analog input on the MOD pin, offering a 0% to 100% range for the -1 variant. It features a CMOS output driver capable of sourcing or sinking 20mA and is housed in a 6-lead Plastic TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0% to 100% duty cycle range

• CMOS output driver sources/sinks 20mA
• Single supply operation from 2.25V to 5.5V

Programmable Timers And Oscillators Applications

• PWM servo loops
• Heater control
• LED dimming control
• Portable and battery-powered equipment

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the IS6 designation corresponds to the Industrial temperature grade (-40°C to 85°C) and the S6 package type (TSOT-23). Ensure compatibility with automotive requirements if applicable, as standard versions differ from AEC-Q100 qualified parts.

Programmable Timers And Oscillators Selection Notes

Select the -1 suffix variant for applications requiring a full 0% to 100% duty cycle range. Choose the IS6 package for industrial temperature operations between -40°C and 85°C. Use the HS6 variant for extended temperatures up to 125°C. Consider the DIV pin configuration for required frequency division ratios and output polarity inversion.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes variants -1, -2, -3, and -4 differing primarily in duty cycle limits. The IS6 prefix denotes the Industrial temperature grade and TSOT-23 package. Other packages include DFN (DCB) and Automotive qualified versions with #W suffixes.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6992HS6-1#TRPBF for higher temperature operation or LTC6992IDCB-1#TRPBF for DFN packaging. Verify duty cycle limits match application needs, as other variants like -2 restrict the range to 5%-95%.
