Product details
Overview
LTC6992MPS6-2#TRMPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precision analog duty cycle control. It delivers 5% to 95% programmable duty cycle range, operates from 2.25V to 5.5V supply, achieves ±1.7% max frequency error over –55°C to 125°C, and features CMOS output sourcing/sinking 20mA - used in LED dimming, heater control, and servo loops requiring stable timing under wide temperature extremes.
For engineers reviewing the LTC6992MPS6-2#TRMPBF datasheet, LTC6992MPS6-2#TRMPBF pinout, LTC6992MPS6-2#TRMPBF application, or LTC6992MPS6-2#TRMPBF equivalent, this page provides verified package mapping (TSOT-23-6), confirmed MOD/SET/DIV pin roles, duty-cycle clamping behavior at 5%/95%, and validated automotive-grade thermal performance up to 125°C junction temperature.
Technical Context
The LTC6992MPS6-2#TRMPBF implements a master oscillator with fixed 1MHz reference scaled by RSET (50kΩ–800kΩ) and an internal 4-bit A/D converter on the DIV pin to select NDIV = 1, 4, 16, 64, 256, 1024, 4096, or 16384. Its PWM generation uses analog voltage input (0.1·VSET to 0.9·VSET) on MOD pin to linearly set duty cycle within 5%–95% bounds.
VSET is internally regulated to 1.00V ±30mV across temperature, enabling frequency programming independent of supply drift. The device integrates power-on reset, digital filtering, polarity inversion (POL bit), and halt-on-low-ISET functionality - all operating without external clock or microcontroller intervention.
Key Specifications
