LTC6992IS6-4#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-4#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 2.25V to 5.5V supply with a typical current consumption of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, determined by an external resistor RSET and an internal programmable divider NDIV (1 to 16384). Duty cycle control is achieved via a 0V to 1V analog input on the MOD pin. This specific variant supports a duty cycle range of 5% to 100%. It features a CMOS output driver capable of sourcing or sinking 20mA and is housed in a 6-lead SOT-23 package.

Programmable Timers And Oscillators Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm the part marking 'L TFCS' matches the SOT-23 package specification. Ensure the ordering suffix #TRMPBF corresponds to the mini tape and reel packaging format required for surface mount assembly processes.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992IS6-4 variant specifically when a 5% to 100% duty cycle range is required. The 'I' grade indicates operation within -40°C to +85°C. The 'S6' designation confirms the SOT-23-6 package. Verify that the application does not require 0% duty cycle, as this version clamps at 5% minimum.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes four variants differentiated by their duty cycle limits. The IS6-4 model is part of the industrial temperature grade (-40°C to +85°C) lineup. It shares the same core architecture and pinout with other TimerBlox devices but offers specific duty cycle constraints suitable for applications requiring full high-side drive capability without reaching zero percent.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements include other LTC6992 variants with different duty cycle limits (e.g., LTC6992IS6-1 for 0%-100%) if the 5% minimum constraint can be relaxed. Cross-model substitution requires verifying the duty cycle range compatibility and ensuring the operating temperature range meets system requirements.
