LTC6992HS6-4#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HS6-4#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 supply of 2.25V to 5.5V with a typical supply current of 365µA at 100kHz. The output frequency ranges from 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 features a PWM duty cycle range of 5% to 100%, is housed in a 6-lead TSOT-23 package, and supports an operating temperature range of –40°C to 125°C.

Programmable Timers And Oscillators Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the ordering suffix #TRMPBF corresponds to the mini tape and reel packaging format containing 500 units. Ensure the specified temperature grade (H) and package type (S6/TSOT-23) match the design requirements before finalizing procurement orders.

Programmable Timers And Oscillators Selection Notes

Select the LTC6992HS6-4 variant when a 5% to 100% duty cycle range is required. The 'H' suffix indicates operation up to 125°C, suitable for industrial environments. The 'S6' denotes the TSOT-23 package. Use the TimerBlox Web-Based Design Tool to calculate precise RSET and DIV resistor values for target frequency and divider settings.

Programmable Timers And Oscillators Part Context

This part belongs to the LTC6992-1/2/3/4 series, which shares identical electrical characteristics and pinouts but differs in duty cycle limits. The -4 version specifically allows oscillations to reach 100% duty cycle while maintaining a 5% minimum limit. It is part of the broader TimerBlox family of versatile silicon timing devices designed for simple configuration using passive components.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6992CS6-4#TRMPBF (commercial temp), LTC6992IS6-4#TRMPBF (industrial temp), and LTC6992MPS6-4#TRMPBF (military temp). Automotive qualified versions are available as LTC6992HS6-4#WTRMPBF. Verify temperature range and package compatibility when substituting.
