LTC6992IS6-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-1#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 supply of 2.25V to 5.5V with a typical supply current of 365µA at 5V. 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, offering a 0% to 100% range for the -1 variant. The device features a CMOS output capable of sourcing or sinking 20mA and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Heater control systems
• LED dimming control
• Portable and battery-powered equipment

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel mini packaging containing 500 units. Confirm the IS6 designation corresponds to the industrial temperature grade (-40°C to 85°C) and the S6 package type (TSOT-23). Ensure compatibility with automotive requirements if applicable, as standard versions differ from AEC-Q100 qualified parts marked with a W suffix.

Programmable Timers And Oscillators Selection Notes

Select the -1 suffix variant to ensure a full 0% to 100% duty cycle range. Choose the IS6 grade for industrial applications requiring operation between -40°C and 85°C. For higher temperature environments up to 125°C, consider the HS6 variant. Ensure the MOD pin input capacitance remains low to maintain stability and minimize jitter effects on the modulation signal.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 family, which includes four variants distinguished by their minimum and maximum duty cycle limits. The -1 version uniquely supports both 0% and 100% duty cycles. Other family members include the -2 (5%-95%), -3 (0%-95%), and -4 (5%-100%) options. All share the same core oscillator architecture and pinout configuration.

Programmable Timers And Oscillators Replacement Considerations

Direct functional replacements within the same family include LTC6992CS6-1#TRMPBF for commercial temperature range or LTC6992HS6-1#TRMPBF for extended high-temperature operation. Cross-package equivalents such as the DFN version LTC6992IDCB-1#TRMPBF are available but require footprint adaptation.
