Product details
Overview
LTC6992HS6-4#TRPBF from Analog Devices is a voltage-controlled pulse width modulator (PWM) IC in the TimerBlox family, designed for precision analog duty-cycle control with 5% to 100% output range. It operates from 2.25V to 5.5V, delivers ±2.4% frequency accuracy over –40°C to 125°C, supports NDIV division ratios up to 16384, and features CMOS output sourcing/sinking 20mA - used in LED dimming, heater control, and servo loops where automotive-grade thermal stability is required.
For engineers reviewing the LTC6992HS6-4#TRPBF datasheet, LTC6992HS6-4#TRPBF pinout, LTC6992HS6-4#TRPBF application, or LTC6992HS6-4#TRPBF equivalent, this page provides verified package mapping (SOT-23-6), confirmed MOD/SET/DIV pin functions, duty-cycle clamping behavior at 5%/100%, supply current vs. frequency curves, and AEC-Q100-compliant operating temperature validation.
Technical Context
The LTC6992HS6-4#TRPBF implements a master oscillator (fMASTER = 1 MHz × 50 kΩ / RSET) followed by an 8-step programmable divider (NDIV = 1, 4, 16…16384), enabling output frequencies from 3.81 Hz to 1 MHz. Its analog PWM control uses a 0 V to 1 V input on the MOD pin referenced to VSET ≈ 1.00 V, with internal voltage limiting ensuring precise 5% minimum and 100% maximum duty cycle enforcement.
It integrates a 4-bit A/D converter on the DIV pin to select NDIV and polarity (POL), a regulated SET pin (1.00 V ±30 mV) with ISET = 1.25 µA–20 µA, and a digital filter to suppress noise-induced jitter. The device achieves <1.7% max frequency error and <3.7% max PWM duty cycle error across its full –40°C to 125°C operating range.

Pinout & Package
Package: 6-lead TSOT-23 (S6), 1 mm height, RoHS-compliant, lead-free finish. Thermal resistance θJA = 192°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts 2.25 V–5.5 V; requires local 0.1 µF bypass to GND for low-noise operation. |
| DIV | Programmable divider & polarity select | 4-bit A/D input; resistor divider sets NDIV (1–16384) and output polarity (POL bit). |

Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM | 0 V–1 V analog input directly maps to 5%–100% duty cycle with <3.7% error - simplifies DAC-less brightness/heat control. |
| Configurable frequency divider | 8 discrete NDIV ratios (1, 4, 16…16384) selected via resistor divider on DIV pin - enables single-part coverage of wide timing ranges. |
| AEC-Q100 qualified | Grade H (–40°C to 125°C) qualification - meets automotive reliability requirements without derating or additional testing. |
| Low-power operation | 105 µA typical supply current at RSET = 800 kΩ and NDIV ≥ 16 - extends battery life in portable medical and sensor devices. |
| Stable 1 V reference | VSET = 1.00 V ±30 mV with ±75 µV/°C drift - decouples frequency accuracy from supply and temperature variations when using RSET. |

FAQ
What is the duty cycle range of the LTC6992HS6-4#TRPBF?
The LTC6992HS6-4#TRPBF provides a 5% to 100% duty cycle range. This means the output cannot go fully off (0%), preventing unintended shutdown in heater or motor control, while supporting full-on operation for maximum power delivery. The clamping behavior is hard-coded into the LTC6992-4 variant and applies across all operating conditions including –40°C to 125°C.
How do I set the output frequency of the LTC6992HS6-4#TRPBF?
You set the output frequency of the LTC6992HS6-4#TRPBF using two elements: a resistor RSET (50 kΩ to 800 kΩ) between the SET pin and GND to define the master oscillator frequency, and a resistor divider on the DIV pin to select one of eight NDIV values (1, 4, 16…16384). The final fOUT = 1 MHz × 50 kΩ / (NDIV × RSET), with ±2.4% total accuracy over temperature.
Is the LTC6992HS6-4#TRPBF AEC-Q100 qualified?
Yes, the LTC6992HS6-4#TRPBF is AEC-Q100 qualified for Grade H (–40°C to 125°C), making it suitable for under-hood automotive applications such as engine control, HVAC actuators, and lighting modules. This qualification covers stress testing for temperature cycling, humidity, and mechanical shock - verified by Analog Devices' automotive reliability reports.
What is the supply current consumption of the LTC6992HS6-4#TRPBF at 100 kHz?
At 100 kHz output frequency, the LTC6992HS6-4#TRPBF draws approximately 115 µA typical supply current when powered from 2.25 V with RSET = 50 kΩ and NDIV = 1. Current scales inversely with RSET and NDIV; using RSET = 800 kΩ reduces quiescent current to ~105 µA, enabling ultra-low-power operation in always-on subsystems.
Can the LTC6992HS6-4#TRPBF drive an LED directly?
Yes, the LTC6992HS6-4#TRPBF can drive an LED directly via its CMOS output, which sources/sinks up to ±20 mA. For safe operation, add a series current-limiting resistor to ensure peak current stays within both the LED's rating and the IC's 20 mA absolute maximum. At V+ = 3.3 V, a 100 Ω resistor limits current to ~33 mA - so use ≥165 Ω to stay within spec. Avoid capacitive loads >5 pF to maintain output edge integrity.
