LTC6992IS6-2#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-2#TRMPBF is a silicon oscillator featuring voltage-controlled pulse width modulation (PWM) capability, part of the TimerBlox family. It operates on a single 2.25V to 5.5V supply with a typical supply current of 115µA at 100kHz. The output frequency ranges from 3.81Hz to 1MHz, determined by an internal master oscillator and a programmable divider (NDIV). The duty cycle is controlled by a 0V to 1V analog input on the MOD pin. This specific variant provides a PWM duty cycle range of 5% to 95%. It is housed in a 6-lead Plastic TSOT-23 package and is specified for an operating temperature range of –40°C to 85°C.

Programmable Timers And Oscillators Feature Summary

• Voltage-Controlled PWM: Duty cycle is set by a simple 0V to 1V analog input on the MOD pin.
• Configurable Frequency: Output frequency ranges from 3.81Hz to 1MHz using one resistor (RSET) and a programmable divider (NDIV = 1 to 16384).
• Defined Duty Cycle Limits: The -2 suffix specifies a minimum duty cycle of 5% and a maximum of 95%, preventing oscillation stoppage at extremes.
• Low Power Consumption: Typical supply current is 115µA at 100kHz, with a fast start-up time of 500µs.

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 ordering suffix #TRMPBF indicates Mini Tape and Reel packaging. Confirm the IS6 designation corresponds to the Industrial temperature grade (-40°C to 85°C) and the SOT-23-6 package. Ensure the -2 suffix matches the required 5% to 95% duty cycle limits for the specific application design.

Programmable Timers And Oscillators Selection Notes

Select this component when a 5% to 95% duty cycle window is required to avoid signal cessation at limits. Choose based on the required frequency range and NDIV setting. For applications requiring 0% or 100% duty cycle capability, consider the -1 or -4 variants. Verify that the SOT-23-6 package fits the PCB layout constraints.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6992 family of TimerBlox silicon oscillators. The 'I' denotes the industrial temperature grade, 'S6' indicates the SOT-23-6 package, and '-2' specifies the 5%-95% duty cycle range. Other variants include -1 (0%-100%), -3 (0%-95%), and -4 (5%-100%).

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6992IS6-1#TRMPBF, LTC6992IS6-3#TRMPBF, and LTC6992IS6-4#TRMPBF, differing only in duty cycle clamp limits. Cross-package equivalents are available in DFN format (e.g., LTC6992IDCB-2#TRMPBF).
