LTC6992HS6-1#WTRPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-1#WTRPBF 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 100kHz. The device generates a PWM signal with a frequency range of 3.81Hz to 1MHz, determined by an external resistor (RSET) and an internal programmable divider (NDIV). The 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 TSOT-23-6 package.

Programmable Timers And Oscillators Procurement Notes

Verify the automotive grade designation indicated by the #W suffix in the part number. Confirm the HS6 suffix corresponds to the high-temperature (-40°C to 125°C) TSOT-23-6 package variant. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Check manufacturer documentation for specific reliability reports associated with the W-series parts.

Programmable Timers And Oscillators Selection Notes

Select this model when a full 0% to 100% duty cycle range is required, as other variants (LTC6992-2/3/4) clamp between 5% and 95%. Choose the HS6 package for applications requiring operation up to 125°C. Use the DIV pin to configure the frequency divider ratio (1 to 16384) and output polarity. Ensure RSET values are within the 50kΩ to 800kΩ range for proper oscillator function.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 family of TimerBlox silicon oscillators. The -1 suffix denotes the version with 0% to 100% duty cycle limits. The HS6 indicates the high-temperature grade and TSOT-23-6 thin SOT package. The #W suffix signifies automotive qualification under AEC-Q100 standards. Other family members include DFN packages and different duty cycle clamping options.

Programmable Timers And Oscillators Replacement Considerations

Direct functional substitutes within the same family include LTC6992IS6-1#WTRPBF (same function, lower temperature grade -40°C to 85°C) or LTC6992HS6-1#TRMPBF (same function/temp, cut tape packaging). For different duty cycle ranges, consider LTC6992HS6-2#WTRPBF (5%-95%) or LTC6992HS6-4#WTRPBF (5%-100%). Package changes require schematic review.
