LTC6992HS6-3#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-3#TRMPBF is a voltage-controlled pulse width modulator (PWM) from Analog Devices, operating within a supply range of 2.25V to 5.5V. It generates PWM signals with frequencies ranging from 3.81Hz to 1MHz, determined by an external resistor on the SET pin and an internal divider. The duty cycle is linearly controlled by a 0V to 1V analog input on the MOD pin. This specific variant supports a duty cycle range of 0% to 95%, features a CMOS output capable of sourcing or sinking 20mA, and operates across an extended temperature range of -40°C to +125°C in a TSOT-23-6 package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM generation via 0V to 1V analog input on the MOD pin
• Frequency range of 3.81Hz to 1MHz set by a single external resistor
• Duty cycle limits of 0% minimum and 95% maximum
• CMOS output driver with 20mA source/sink capability

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 component matches the specified automotive-grade suffix (#W) if required for high-reliability applications, as standard versions lack this designation. Confirm the package type is TSOT-23-6 and the temperature grade is H (-40°C to +125°C). Ensure the duty cycle variant corresponds to the -3 suffix (0% to 95%) rather than other options like -1 or -2. Check RoHS compliance status through official manufacturer documentation before finalizing procurement.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992HS6-3#TRMPBF when a 0% to 95% duty cycle range is required. The 'H' suffix indicates operation up to 125°C, suitable for harsh environments. The 'S6' denotes the TSOT-23-6 package. The '#TRMPBF' indicates tape and reel packaging with lead-free finish. Consider the #W suffix if automotive qualification is necessary. Ensure the application requires a voltage-controlled duty cycle rather than fixed frequency modulation.

Programmable Timers And Oscillators Part Context

This part belongs to the TimerBlox family of silicon timing devices. It is one of four variants differing only in duty cycle limits: -1 (0%-100%), -2 (5%-95%), -3 (0%-95%), and -4 (5%-100%). The HS6-3 variant specifically combines the high-temperature grade with the TSOT-23-6 package and the 0%-95% duty cycle constraint.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements include other LTC6992 variants with different duty cycle limits (-1, -2, -4) if the 0%-95% constraint is not critical. Automotive-grade equivalents are available with the #W suffix (e.g., LTC6992HS6-3#WTRMPBF). Other packages like DFN (DCB) are electrically compatible but require mechanical adaptation.
