Product details
Overview
LTC6992HDCB-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% programmable duty cycle range, operates from 2.25V to 5.5V supply, achieves ±1.7% max frequency error over –40°C to 125°C, and features CMOS output sourcing/sinking 20mA - used in LED dimming, heater control, and servo loops requiring stable timing under high-temperature conditions.
For engineers reviewing the LTC6992HDCB-2#TRPBF datasheet, LTC6992HDCB-2#TRPBF pinout, LTC6992HDCB-2#TRPBF application, or LTC6992HDCB-2#TRPBF equivalent, this page provides verified package mapping (6-lead DFN, 2mm × 3mm), confirmed MOD/SET/DIV pin functions, duty-cycle clamping behavior (5%/95%), and validated automotive-grade thermal performance (–40°C to 125°C).
Technical Context
The LTC6992HDCB-2#TRPBF implements a master oscillator with fixed 1MHz reference scaled by RSET (50kΩ–800kΩ), followed by an internal 4-bit A/D converter on the DIV pin selecting NDIV = 1, 4, 16, ..., 16384. Its PWM generation uses a voltage-limited linear transfer function: duty cycle = (VMOD(LIM) − 0.1·VSET) / 0.8·VSET, where VMOD(LIM) clamps at 0.1·VSET (5%) and 0.9·VSET (95%).
VSET is regulated to 1.00V ±30mV across temperature, enabling RSET-based frequency programming independent of VSET drift. The device includes power-on reset, 500µs startup time, and digital filtering to suppress noise on the MOD and DIV inputs - critical for robust operation in high-vibration industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Duty Cycle Range | 5% to 95% - ensures safe switching margins for MOSFET gate drivers and avoids full-on/full-off states in motor or heater control. |
| Frequency Range | 3.81Hz to 1MHz - supports ultra-low-power sleep-mode timing (e.g., 3.81Hz watchdog) and high-speed LED dimming (1MHz). |
| Max Frequency Error | ±1.7% over –40°C to 125°C - guarantees stable PWM period without recalibration in automotive under-hood applications. |
| Supply Voltage | 2.25V to 5.5V - enables direct interface with Li-ion battery systems (2.7V–4.2V) and 3.3V/5V logic without level-shifting. |
| MOD Pin Input Range | 0.1·VSET to 0.9·VSET (≈100mV–900mV) - allows simple 0–1V DAC or potentiometer interface with built-in clamping. |
| Operating Temperature | –40°C to 125°C - qualified per AEC-Q100 Grade H, suitable for engine control units and industrial PLCs. |
| Supply Current | 105µA to 450µA - scales with NDIV and RSET; enables <150µA operation at low frequencies for battery longevity. |
Pinout & Package
Package: 6-lead (2mm × 3mm) plastic DFN (DCB), exposed pad (Pin 7) connected to GND. RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 6) | Digital PWM output | CMOS rail-to-rail driver capable of sourcing/sinking 20mA; requires series resistor when driving LEDs or MOSFET gates directly. |
| GND (Pin 2) | Analog/digital ground reference | Low-inductance connection point for 0.1µF bypass capacitor; exposed pad must be soldered to PCB ground plane for thermal and EMI performance. |
| MOD (Pin 1) | Analog duty cycle control input | Accepts 0.1·VSET to 0.9·VSET (≈100mV–900mV); clamps output at 5% or 95% beyond this range - no external protection needed. |
| V+ (Pin 5) | Power supply input | 2.25V–5.5V operation; must be bypassed locally with 0.1µF ceramic capacitor to GND to suppress switching noise coupling into SET/MOD pins. |
| DIV (Pin 4) | Divider ratio and polarity select | Voltage-programmed via resistor divider; sets NDIV (1–16384) and output polarity (POL bit); ≤100pF capacitance required for accurate A/D conversion. |
| SET (Pin 3) | Frequency-setting input | Regulated to 1.00V; ISET = VSET/RSET programs master oscillator - RSET = 50kΩ–800kΩ yields fOUT = 1MHz·50k/(NDIV·RSET). |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-controlled PWM with analog input | Direct 0.1·VSET–0.9·VSET modulation enables seamless integration with DACs, sensors, or op-amp outputs without microcontroller intervention. |
| Programmable frequency divider (NDIV) | Eight discrete division ratios (1, 4, 16, ..., 16384) selected via DIV pin voltage - eliminates need for external counters or clock dividers in timing-critical systems. |
| Automotive-grade temperature range | –40°C to 125°C operation with guaranteed specs - supports placement near engines, inverters, or power electronics without derating. |
| Low quiescent current | As low as 105µA at V+ = 2.25V, RSET = 800kΩ, NDIV ≥ 16 - extends battery life in portable medical or IoT edge devices. |
| Integrated power-on reset and startup stabilization | 500µs typical startup time with output disabled until internal references settle - prevents spurious pulses during power ramp-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-controlled PWM applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6992HDCB-1#TRPBF | 0%–100% duty cycle range; no 5%/95% clamping - allows full-on/off states and oscillator halt at extremes. | Suitable for applications requiring zero-output standby (e.g., power gating) or 100% drive (e.g., solenoid activation). | Select LTC6992HDCB-1#TRPBF only if system design explicitly requires duty cycle beyond 5–95% bounds. |
| LTC6992HDCB-3#TRPBF | 0%–95% duty cycle; minimum duty cycle = 0%, maximum = 95% - retains 0% capability while limiting upper bound like -2 variant. | Preferred for servo systems needing full-off state but requiring safe upper limit to prevent overtravel or overheating. | Choose LTC6992HDCB-3#TRPBF when 0% duty cycle is mandatory but 100% is unsafe - e.g., bidirectional motor control with braking. |
Compared with LTC6992HDCB-1#TRPBF and LTC6992HDCB-3#TRPBF, the LTC6992HDCB-2#TRPBF uniquely enforces symmetrical 5%/95% clamping - simplifying safety-critical designs where both minimum and maximum conduction must be bounded to prevent component stress or thermal runaway.

FAQ
What is the exact duty cycle range supported by the LTC6992HDCB-2#TRPBF?
The LTC6992HDCB-2#TRPBF supports a precisely defined 5% to 95% duty cycle range. This is enforced by internal voltage clamping: when the MOD pin voltage falls below 0.1·VSET (~100mV), output duty cycle is held at 5%; above 0.9·VSET (~900mV), it clamps at 95%. This behavior is guaranteed across the full –40°C to 125°C operating range and eliminates risk of 0% or 100% output in safety-critical systems.
How does the LTC6992HDCB-2#TRPBF achieve frequency stability over temperature?
The LTC6992HDCB-2#TRPBF achieves ±1.7% max frequency error over –40°C to 125°C through a combination of on-chip VSET regulation (1.00V ±30mV), low-drift RSET resistor programming, and internal compensation. Its master oscillator equation fOUT = 1MHz·50k/(NDIV·RSET) isolates frequency accuracy from VSET drift, making RSET tolerance and inherent IC error the dominant contributors - both tightly controlled in the H-grade version.
Can the LTC6992HDCB-2#TRPBF operate from a 2.5V supply?
Yes, the LTC6992HDCB-2#TRPBF operates from 2.25V to 5.5V, fully supporting 2.5V systems. At V+ = 2.25V, it delivers 20mA output drive capability, maintains 5%–95% duty cycle accuracy, and draws as little as 105µA supply current (with RSET = 800kΩ and NDIV ≥ 16). Output high/low voltages are specified down to 2.25V, ensuring compatibility with 2.5V logic families.
What is the purpose of the DIV pin on the LTC6992HDCB-2#TRPBF?
The DIV pin on the LTC6992HDCB-2#TRPBF serves dual functions: it selects the programmable frequency divider ratio (NDIV = 1, 4, 16, ..., 16384) via an internal 4-bit A/D converter, and determines output polarity (POL bit). A resistor divider between V+ and GND sets VDIV to encode DIVCODE; for example, VDIV/V+ = 0.03125 selects NDIV = 1 and non-inverted output. Capacitance on this pin must remain below 100pF for reliable conversion.
Is the LTC6992HDCB-2#TRPBF qualified for automotive applications?
Yes, the LTC6992HDCB-2#TRPBF is AEC-Q100 qualified for automotive applications (Grade H), with guaranteed operation from –40°C to 125°C and tested reliability per automotive stress standards. Its DFN package, low EMI sensitivity, and built-in power-on reset make it suitable for under-hood modules, body control units, and ADAS subsystems where long-term timing stability and thermal resilience are critical.
