LTC6992HS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-1#TRMPBF 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 device features an output frequency range of 3.81Hz to 1MHz, determined by a master oscillator and an internal divider programmable via the DIV pin. PWM duty cycle is controlled by a 0V to 1V analog input on the MOD pin. This specific variant supports a 0% to 100% duty cycle range and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0% to 100% duty cycle range
• Frequency range of 3.81Hz to 1MHz using a single resistor
• Internal programmable divider (NDIV) for frequency scaling
• CMOS output driver capable of sourcing/sinking 20mA

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 automotive grade suffix (#W) if AEC-Q100 qualification is required, as standard parts may differ. Confirm the SOT-23-6 package type matches the design footprint. Ensure the 0% to 100% duty cycle specification aligns with application requirements, as other variants in the series have different limits.

Programmable Timers And Oscillators Selection Notes

Select this part for applications requiring full 0% to 100% duty cycle coverage. The HS6-1 designation indicates high temperature operation (-40°C to 125°C) and the -1 suffix specifies the duty cycle limits. Consider the NDIV settings available via the DIV pin for precise frequency division needs.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 family, which includes four versions differing primarily in their minimum and maximum duty cycle limits. The LTC6992-1 variant specifically allows oscillations to reach 0% and 100%, whereas other models clamp at 5% or 95%. It is part of the broader TimerBlox silicon timing device portfolio.

Programmable Timers And Oscillators Replacement Considerations

LTC6992IS6-1#TRMPBF offers identical electrical characteristics but with a lower operating temperature range of –40°C to 85°C instead of –40°C to 125°C.
