Product details
Overview
LTC6992HS6-2#TRPBF 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% adjustable PWM output with ±3.7% max duty cycle error, 3.81Hz–1MHz frequency range, and operates from 2.25V–5.5V supply. Used in LED dimming, heater control, and servo loops where stable, low-drift timing is critical.
For engineers reviewing the LTC6992HS6-2#TRPBF datasheet, LTC6992HS6-2#TRPBF pinout, LTC6992HS6-2#TRPBF application, or LTC6992HS6-2#TRPBF equivalent, this page provides verified package mapping (SOT-23-6), confirmed pin functions (MOD/SET/DIV/OUT/V+/GND), temperature-rated performance (–40°C to 125°C), and validated alternatives for automotive-grade PWM control designs.
Technical Context
The LTC6992HS6-2#TRPBF integrates a master oscillator (1MHz max) with a programmable divider (NDIV = 1, 4, 16, ..., 16384) and a 4-bit A/D converter on the DIV pin to select both division ratio and polarity. Its SET pin regulates VSET to 1.00V ±30mV, enabling frequency programming via RSET (50kΩ–800kΩ) with <1.7% total error over temperature.
Duty cycle is linearly controlled by VMOD (0.1•VSET to 0.9•VSET), clamped at 5% min / 95% max per its -2 variant designation. The CMOS output sources/sinks 20mA with 1.1ns rise time (V+ = 5.5V), and internal power-on reset ensures clean startup in <500µs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled PWM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TLC555IP | 555 timer with external RC network; no integrated VSET regulation or NDIV divider; ±5% duty cycle linearity; no AEC-Q100 rating | Requires external op-amp for 0–1V MOD scaling; limited to 100kHz max; not qualified for automotive use | Choose only for cost-sensitive, non-automotive, low-frequency (<10kHz) applications where ±5% duty error is acceptable |
| Microchip MIC5014YM5-TR | Dedicated PWM controller with fixed 50%–100% range; no analog voltage input; requires external oscillator; no temperature-compensated VSET | Designed for DC-DC gate driving-not for analog-modulated loads like heaters or LEDs | Select only when duty cycle must be strictly bounded above 50% and system already uses external clock source |
Compared with TLC555IP and MIC5014YM5-TR, the LTC6992HS6-2#TRPBF uniquely combines AEC-Q100 qualification, 5%–95% analog-controlled duty cycle, integrated frequency programming, and sub-2% frequency drift-making it the sole option for automotive and industrial PWM where hardware-level reliability and precision are mandatory.

FAQ
What is the maximum operating temperature for the LTC6992HS6-2#TRPBF?
The LTC6992HS6-2#TRPBF is rated for continuous operation from –40°C to +125°C and is AEC-Q100 qualified for automotive Grade H applications. This specification is guaranteed across the full temperature range, with all key parameters-including frequency accuracy (±1.7%), duty cycle error (±3.7%), and supply current-validated at 125°C junction temperature.
How does the LTC6992HS6-2#TRPBF achieve 5% to 95% duty cycle limits?
The LTC6992HS6-2#TRPBF implements hard clamping in silicon: when VMOD falls below 0.10•VSET (~100mV), the output holds at 5%; when VMOD exceeds 0.86•VSET (~860mV), it clamps at 95%. This behavior is intrinsic to the -2 variant and eliminates external circuitry needed to prevent 0% or 100% duty cycles in heater or LED drivers.
Can the LTC6992HS6-2#TRPBF be used with a 2.25V supply?
Yes-the LTC6992HS6-2#TRPBF operates fully specified down to 2.25V. At this voltage, it delivers 105µA typical supply current (RSET = 800kΩ, NDIV ≥ 16), maintains ±3.7% duty cycle accuracy, and sustains CMOS output drive (8mA sink/source). Output high/low voltages remain rail-to-rail compliant per Logic IC Standard.
What is the role of the DIV pin on the LTC6992HS6-2#TRPBF?
The DIV pin on the LTC6992HS6-2#TRPBF connects to an internal 4-bit A/D converter referenced to V+. A resistor divider between V+ and GND sets VDIV, which determines both the frequency division ratio (NDIV = 1, 4, 16, ..., 16384) and output polarity (POL bit). No external logic or MCU is required-configuration is purely analog and static.
Is the LTC6992HS6-2#TRPBF pin-compatible with other TimerBlox variants?
Yes-all TimerBlox LTC6992 variants (including -1, -2, -3, -4) in the S6 (TSOT-23-6) package share identical pinout, footprint, and electrical interface. The only functional difference is the duty cycle clamp range, selected at manufacture; swapping LTC6992HS6-2#TRPBF for LTC6992HS6-1#TRPBF requires no PCB changes but alters min/max duty behavior.
