LTC6992HS6-4#WTRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-4#WTRMPBF is an automotive-grade silicon oscillator featuring voltage-controlled pulse width modulation (PWM). It operates on a single supply from 2.25V to 5.5V with a typical supply current of 365µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, determined by a master oscillator and an internal divider programmable from 1 to 16384. This specific variant provides a duty cycle range of 5% to 100%, controlled by a 0V to 1V analog input on the MOD pin. It utilizes a TSOT-23-6 package and supports a -40°C to 125°C operating temperature range.

Programmable Timers And Oscillators Feature Summary

• Automotive qualified (AEC-Q100) with extended temperature range (-40°C to 125°C)
• Voltage-controlled PWM with 5% to 100% duty cycle limits
• Frequency range of 3.81Hz to 1MHz via external resistor programming
• 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 #W suffix indicates automotive grade manufacturing controls. Confirm the HS6 designation corresponds to the high-temperature industrial range and TSOT-23-6 package. Ensure the -4 suffix matches the required 5% to 100% duty cycle window for the specific application design.

Programmable Timers And Oscillators Selection Notes

Select this part when automotive reliability and wide temperature operation are required. The -4 suffix restricts the minimum duty cycle to 5%, preventing oscillation stoppage at low settings. Use the TimerBlox design tool to calculate RSET and DIV resistor values for precise frequency and duty cycle targeting.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of silicon timing devices. It shares core architecture with the LTC6992-1, -2, and -3 variants, differing primarily in duty cycle limits and temperature grades. The HS6-4 configuration specifically targets applications requiring high-temperature stability and a non-zero minimum duty cycle.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes include other LTC6992 variants with adjusted duty cycle limits or temperature grades. Verify package compatibility between TSOT-23-6 and alternative footprints if cross-referencing DFN versions.
