LTC6992IS6-4#TRPBF

Programmable Timers And Oscillators Overview

The LTC6992IS6-4#TRPBF is a silicon oscillator and voltage-controlled pulse width modulator 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 115µA at 100kHz. The device generates PWM signals with a frequency range of 3.81Hz to 1MHz, determined by an external resistor (RSET) and an internal programmable divider (NDIV). Duty cycle is controlled via a 0V to 1V analog input on the MOD pin. This specific variant (suffix -4) supports a duty cycle range of 5% to 100%. It features a CMOS output driver capable of sourcing and sinking 20mA and is housed in a 6-lead TSOT-23 package.

Programmable Timers And Oscillators Feature Summary

• Duty cycle limits of 5% minimum and 100% maximum
• CMOS output driver sources/sinks 20mA

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 #TRPBF indicates tape and reel packaging. Confirm the IS6 designation corresponds to the industrial temperature range (-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.

Programmable Timers And Oscillators Selection Notes

Select this part when a 5% to 100% duty cycle range is required. The -4 suffix defines these specific limits compared to other variants like -1 (0%-100%) or -2 (5%-95%). Ensure the application requires the industrial temperature grade (-40°C to 85°C) and the TSOT-23 package form factor.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992-1/2/3/4 family of TimerBlox silicon oscillators. The 'I' denotes the industrial temperature grade, 'S6' indicates the 6-lead TSOT-23 package, and '-4' specifies the 5% to 100% duty cycle operational limits. It is distinct from the C (commercial), H (high temp), and MP (military) grades.

Programmable Timers And Oscillators Replacement Considerations

Direct substitutes within the same family include LTC6992IS6-1#TRPBF (0%-100% duty cycle), LTC6992IS6-2#TRPBF (5%-95% duty cycle), and LTC6992IS6-3#TRPBF (0%-95% duty cycle). Package variations such as DFN (DCB) are available but require layout adjustments.
