Product details
Overview
LTC6992MPS6-3#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 0% 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 capable of sourcing/sinking 20mA - used in LED dimming and heater control circuits requiring stable timing under wide temperature extremes.
For engineers reviewing the LTC6992MPS6-3#TRPBF datasheet, LTC6992MPS6-3#TRPBF pinout, LTC6992MPS6-3#TRPBF application, or LTC6992MPS6-3#TRPBF equivalent, this page provides verified package mapping (TSOT-23-6), confirmed MOD/SET/DIV pin functions, duty-cycle clamping behavior at 0%/95%, and validated automotive-grade thermal performance per AEC-Q100 MP-grade specification.
Technical Context
The LTC6992MPS6-3#TRPBF 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 that selects NDIV = 1, 4, 16, 64, 256, 1024, 4096, or 16384. Its PWM transfer function maps VMOD linearly between 0.1·VSET and 0.9·VSET to output duty cycle, with hard clamps at 0% and 95% for the -3 variant.
It integrates power-on reset, 500µs startup time, and a regulated 1V SET pin reference (±30mV) enabling frequency programming independent of VSET drift. The device uses internal digital filtering and polarity inversion (POL bit) to support both standard and inverted PWM waveforms without external logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Duty Cycle Range | 0% to 95% - enables full-off capability and near-full-on operation while preventing output saturation in closed-loop servo systems. |
| Frequency Range | 3.81Hz to 1MHz - supports ultra-low-power battery monitoring (sub-10Hz) and high-speed LED modulation (1MHz) with single RSET tuning. |
| Max Frequency Error | ±1.7% over –55°C to 125°C - ensures timing-critical heater control remains within ±1.7% accuracy across automotive under-hood environments. |
| Supply Voltage Range | 2.25V to 5.5V - compatible with Li-ion, 3.3V logic, and 5V industrial rails without level-shifting. |
| Output Drive Strength | ±20mA CMOS - directly drives LEDs, small relays, or MOSFET gates without external buffers. |
| Operating Temperature | –55°C to 125°C - qualified per AEC-Q100 MP grade for engine control, transmission, and ADAS modules. |
| MOD Input Range | 0.1·VSET to 0.9·VSET (≈100mV–900mV) - allows direct interfacing with DACs or op-amp outputs without scaling resistors. |
Pinout & Package
Package: 6-lead Plastic TSOT-23 (S6), 1mm profile, lead-free, RoHS-compliant. Exposed pad not present in S6 package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ (Pin 1) | Power Supply Input | 2.25V–5.5V supply rail; requires local 0.1µF bypass to GND for low-noise operation. |
| DIV (Pin 2) | Programmable Divider & Polarity Control | Resistor-divider input setting NDIV ratio (1–16384) and output polarity (POL bit); ≤100pF capacitance required. |

| MOD (Pin 4) | Analog PWM Control Input | 0.1·VSET to 0.9·VSET linear range sets duty cycle; clamps at 0%/95% for LTC6992-3 variant. |
| GND (Pin 5) | Ground Reference | Low-inductance return path for all internal circuitry; must connect to solid ground plane. |
| OUT (Pin 6) | PWM Output Driver | CMOS push-pull output swinging rail-to-rail (GND to V+); ±20mA drive supports direct load connection. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM with 0%–95% range | Enables zero-power state in heater/LED systems and avoids 100% duty cycle-induced thermal runaway. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled PWM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6992IS6-3#TRPBF | Same functionality and pinout, but rated for –40°C to 85°C (I-grade) instead of –55°C to 125°C (MP-grade). | Not qualified to AEC-Q100 MP requirements; unsuitable for under-hood automotive use. | Select only for commercial/industrial applications where extended temperature range is unnecessary. |
| LTC6992HDCB-3#TRPBF | Same -3 duty-cycle range, but in 2mm × 3mm DFN package with exposed pad (thermal resistance θJC = 10.6°C/W vs SOT-23's 51°C/W). | Higher power dissipation capability; requires PCB thermal pad design; not drop-in compatible with SOT-23 footprint. | Choose when thermal headroom exceeds 150mW or board space permits larger DFN layout. |
Compared with LTC6992IS6-3#TRPBF, the LTC6992MPS6-3#TRPBF offers guaranteed operation down to –55°C and AEC-Q100 MP qualification for automotive deployment; versus LTC6992HDCB-3#TRPBF, it trades thermal performance for compact TSOT-23 size and simplified assembly - ideal for space-constrained engine control modules.

FAQ
What is the duty cycle range of the LTC6992MPS6-3#TRPBF?
The LTC6992MPS6-3#TRPBF provides a 0% to 95% duty cycle range. This means the output can be fully off (0%) or up to 95% on, with hard clamping at both limits - a key distinction from the -1 (0–100%) and -2 (5–95%) variants. This range prevents unintended full-on states in safety-critical heater or motor control applications while retaining true zero-power capability.
How is the output frequency programmed on the LTC6992MPS6-3#TRPBF?
The LTC6992MPS6-3#TRPBF uses a single external resistor (RSET) connected between the SET pin and GND to program frequency. With RSET values from 50kΩ to 800kΩ, the device achieves 3.81Hz to 1MHz output after internal division (NDIV = 1 to 16384). The SET pin maintains a regulated 1V reference, making frequency setting insensitive to supply voltage drift or RSET temperature coefficient errors.
What package type does the LTC6992MPS6-3#TRPBF use?
The LTC6992MPS6-3#TRPBF is housed in a 6-lead Plastic TSOT-23 (S6) package, measuring 2.9mm × 1.6mm × 1.0mm. It is lead-free, RoHS-compliant, and optimized for automated surface-mount assembly. Unlike the DFN variants, the SOT-23 version has no exposed thermal pad and relies on PCB copper for heat dissipation.
Does the LTC6992MPS6-3#TRPBF support AEC-Q100 qualification?
Yes, the LTC6992MPS6-3#TRPBF is AEC-Q100 qualified as an MP-grade part, certified for operation from –55°C to 125°C with full parametric testing across temperature and life stress conditions. This makes it suitable for automotive powertrain, chassis, and ADAS applications where reliability under extreme thermal cycling is mandatory.
What is the maximum output current capability of the LTC6992MPS6-3#TRPBF?
The LTC6992MPS6-3#TRPBF features a rail-to-rail CMOS output stage capable of sourcing and sinking up to ±20mA. This allows direct drive of LEDs, small solenoids, MOSFET gates, or logic inputs without external buffer stages - reducing bill-of-materials cost and PCB area in compact embedded designs.
