LTC6992HS6-1#WTRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-1#WTRMPBF is an automotive-grade silicon oscillator and voltage-controlled pulse width modulator (PWM) from Analog Devices. It operates on a single supply of 2.25V to 5.5V with a frequency range of 3.81Hz to 1MHz. The device features a 0% to 100% duty cycle range controlled by a 0V to 1V analog input on the MOD pin. Key electrical parameters include a maximum frequency error of ±1.7%, supply current of 365µA at 100kHz, and a CMOS output driver capable of sourcing/sinking 20mA. It is housed in a TSOT-23-6 package and qualified under AEC-Q100 standards.

Programmable Timers And Oscillators Feature Summary

• Automotive grade qualification (AEC-Q100)
• Low supply current: 365µA typical at 100kHz

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 specific suffix #WTRMPBF indicates automotive grade manufacturing and tape-and-reel mini packaging. Confirm the HS6 designation corresponds to the high-temperature (-40°C to 125°C) variant in the SOT-23 package. Cross-reference the distributor's part number against the official Analog Devices order information table to ensure correct temperature grade and package type.

Programmable Timers And Oscillators Selection Notes

Select this variant for applications requiring full 0% to 100% duty cycle capability, including oscillation stop at extremes. Ensure the operating environment stays within -40°C to 125°C. Use precision resistors (0.5% tolerance or better) on the SET pin for optimal frequency accuracy. Consider the DIV pin configuration for required frequency division ratios and polarity inversion needs.

Programmable Timers And Oscillators Part Context

This component belongs to the TimerBlox family of versatile silicon timing devices. The LTC6992 series includes four versions differing only in duty cycle limits. The '-1' suffix denotes the 0% to 100% duty cycle option. The 'HS6' indicates the high-temperature grade and TSOT-23-6 package. The '#W' suffix signifies automotive qualification.

Programmable Timers And Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Other variants in the LTC6992 family (e.g., LTC6992HS6-2, -3, -4) share similar electrical characteristics but differ in duty cycle limits.
