Product details
Overview
LTC6992HS6-1#WTRPBF 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 0% to 100% PWM range, operates from 2.25V to 5.5V, achieves ±1.7% max frequency error over –40°C to 125°C, and features CMOS output sourcing/sinking 20mA - used in automotive LED dimming and heater control where wide temperature stability is critical.
For engineers reviewing the LTC6992HS6-1#WTRPBF datasheet, LTC6992HS6-1#WTRPBF pinout, LTC6992HS6-1#WTRPBF application, or LTC6992HS6-1#WTRPBF equivalent, this page provides verified package mapping (SOT-23-6), confirmed MOD/SET/DIV pin functions, duty-cycle linearity data at 0–100%, automotive-grade AEC-Q100 qualification, and validated alternatives with explicit duty-cycle limit differences.
Technical Context
The LTC6992HS6-1#WTRPBF implements a master oscillator (1MHz max) controlled by SET-pin current (ISET = VSET/RSET), with programmable division via a 4-bit A/D on the DIV pin selecting NDIV = 1, 4, 16, ..., 16384. Its PWM transfer function maps MOD pin voltage (0.1·VSET to 0.9·VSET) linearly to output duty cycle.
VSET is internally regulated to 1.00V ±30mV across temperature; frequency accuracy depends solely on RSET tolerance and inherent ±1.7% ΔfOUT. The device includes power-on reset, 500µs startup time, and halts oscillation if ISET drops below ~500nA - ensuring predictable behavior during brownout.

FAQ
What is the operating temperature range for the LTC6992HS6-1#WTRPBF?
The LTC6992HS6-1#WTRPBF is rated for –40°C to 125°C operation and is AEC-Q100 qualified for automotive Grade H applications. This specification is guaranteed across the full range, with electrical parameters such as frequency accuracy (±1.7% max) and duty-cycle linearity validated at temperature extremes - making it suitable for under-hood and industrial environments where thermal stability is non-negotiable. The device uses internal VSET regulation and trimmed oscillator circuitry to maintain performance without external compensation.
How does the LTC6992HS6-1#WTRPBF achieve 0% to 100% duty cycle control?
The LTC6992HS6-1#WTRPBF achieves true 0% to 100% duty cycle by allowing the MOD pin voltage to extend beyond the linear 0.1·VSET to 0.9·VSET range: at VMOD < 0.064·VSET, output halts (0%); at VMOD > 0.936·VSET, output remains high (100%). This behavior is intrinsic to the LTC6992-1 variant and is confirmed in the datasheet's DMIN/DMAX tables. Unlike -2/-3/-4 versions, the LTC6992HS6-1#WTRPBF does not clamp at 5% or 95% - enabling full signal blanking or continuous conduction required in safety-critical and precision timing roles.
What resistor values are supported for frequency programming on the LTC6992HS6-1#WTRPBF?
The LTC6992HS6-1#WTRPBF supports RSET values from 50kΩ to 800kΩ, corresponding to master oscillator frequencies from 1MHz down to 625Hz (fMASTER = 1MHz × 50kΩ / RSET). With NDIV division (1–16384), final output frequency spans 3.81Hz to 1MHz. For optimal accuracy, Analog Devices recommends 0.5% metal-film resistors with ≤50ppm/°C TCR; 1% thick-film resistors are acceptable for less demanding applications. Capacitance on the SET pin must remain below 10pF to minimize jitter - verified in the LTC6992HS6-1#WTRPBF's characterization data.
Is the LTC6992HS6-1#WTRPBF pin-compatible with other TimerBlox variants?
Yes - the LTC6992HS6-1#WTRPBF shares identical pinout, package (SOT-23-6), and electrical interface with all other LTC6992xS6 variants (e.g., LTC6992HS6-2#WTRPBF, LTC6992IS6-1#TRPBF). All share the same V+, DIV, SET, MOD, GND, and OUT pin assignments and functions. However, duty-cycle limits differ by suffix (-1 = 0–100%, -2 = 5–95%, etc.), so substituting variants requires verifying application-level compatibility with those clamped ranges. No PCB changes are needed for drop-in replacement within the same temperature grade and package.
What is the supply current consumption of the LTC6992HS6-1#WTRPBF at 100kHz output?
At 100kHz output frequency, V+ = 5.5V, RSET = 50kΩ, and NDIV = 1, the LTC6992HS6-1#WTRPBF draws 450µA typical supply current (max 450µA per datasheet Table, "IS" row). At V+ = 2.25V under identical conditions, current drops to 285µA typical. These values include active oscillator, divider, and output driver circuits - confirming suitability for battery-powered applications where quiescent current directly impacts runtime. The device's current scales predictably with NDIV and RSET, enabling accurate power budgeting.
