LTC6992HS6-3#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-3#WTRPBF is an automotive-grade silicon oscillator and voltage-controlled pulse width modulator (PWM) from Analog Devices. It operates on a single 2.25V to 5.5V supply with a typical current of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, set by a single resistor RSET and an internal divider NDIV. Duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant provides a duty cycle range of 0% to 95%. It features <1.7% maximum frequency error, CMOS output sourcing/sinking 20mA, and operates within a -40°C to 125°C temperature range in a TSOT-23-6 package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0V to 1V analog input for duty cycle adjustment

Programmable Timers And Oscillators Applications

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

Programmable Timers And Oscillators Procurement Notes

Verify the #W suffix indicates automotive grade qualification and the HS6 designation confirms the high-temperature (-40°C to 125°C) TSOT-23-6 package. Confirm the -3 suffix corresponds to the 0% to 95% duty cycle limit. Ensure the TRPBF suffix matches the required tape and reel packaging quantity for production integration.

Programmable Timers And Oscillators Selection Notes

Select this part when an automotive-rated silicon oscillator with precise analog duty cycle control is required. The -3 variant is suitable if the application requires a 0% minimum duty cycle but must cap the maximum at 95% to prevent oscillation stoppage. Compare against -1 (0-100%), -2 (5-95%), and -4 (5-100%) variants based on specific duty cycle constraints.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of versatile silicon timing devices. The LTC6992 series includes four versions differentiated by their duty cycle limits. The HS6 package variant offers extended temperature performance compared to standard industrial grades, making it appropriate for harsh environments.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6992HS6-1#WTRPBF, LTC6992HS6-2#WTRPBF, and LTC6992HS6-4#WTRPBF. Selection depends on whether the 0% or 5% minimum duty cycle and 95% or 100% maximum duty cycle limits match the design requirements.
