LTC6992HDCB-1#TRMPBF

Programmable Timers And Oscillators Overview

The LTC6992HDCB-1#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 specified temperature range of –40°C to 125°C. The output frequency ranges from 3.81Hz to 1MHz, determined by an external resistor and an internal divider. Duty cycle is controlled via a 0V to 1V analog input on the MOD pin, offering a 0% to 100% range for the -1 variant. Key electrical parameters include a maximum frequency error of ±1.7%, supply current of 115µA at 100kHz, and a CMOS output driver capable of sourcing/sinking 20mA.

Programmable Timers And Oscillators Feature Summary

• Voltage-controlled PWM with 0% to 100% duty cycle range
• Frequency range of 3.81Hz to 1MHz with <1.7% max error
• Configurable using 1 to 3 resistors
• CMOS output driver sources/sinks 20mA

Programmable Timers And Oscillators Applications

• PWM servo loops
• Heater control
• LED dimming control
• Portable and battery-powered equipment

Programmable Timers And Oscillators Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging in mini quantities. Confirm the H grade corresponds to the –40°C to 125°C operating temperature range. Ensure compatibility with the 6-lead DFN package dimensions. Check for automotive qualification requirements if applicable, as standard H grade parts are not AEC-Q100 qualified.

Programmable Timers And Oscillators Selection Notes

Select the -1 suffix variant when a full 0% to 100% duty cycle range is required. Choose the HDCB package for surface mount applications requiring a 2mm x 3mm footprint. Consider the IS6 or HS6 variants if a TSOT-23 package is preferred. Verify that the required frequency accuracy meets the ±1.7% specification over the target temperature range.

Programmable Timers And Oscillators Part Context

This component belongs to the LTC6992 series, which includes four variants (-1, -2, -3, -4) differing primarily in their minimum and maximum duty cycle limits. The HDCB designation specifies the 6-lead plastic DFN package. The H suffix denotes the industrial/high-temperature grade suitable for –40°C to 125°C operation.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same family include LTC6992IDCB-1#TRMPBF for commercial temperature range or LTC6992CDCB-1#TRMPBF for lower temperature applications. Package alternatives include the S6 (TSOT-23) variants such as LTC6992HS6-1#TRMPBF.
