Product details
Overview
LTC6993HS6-4#TRPBF from Analog Devices is a falling-edge-triggered, retriggerable monostable multivibrator (one-shot) IC with programmable pulse width from 1µs to 33.6 seconds. It operates from 2.25V to 5.5V, consumes as low as 65µA at 2.25V/800kΩ, and delivers ±20mA CMOS output drive in a –40°C to 125°C industrial temperature range. It is used in missing-pulse detection and high-vibration envelope detection circuits.
For engineers reviewing the LTC6993HS6-4#TRPBF datasheet, LTC6993HS6-4#TRPBF pinout, LTC6993HS6-4#TRPBF application, or LTC6993HS6-4#TRPBF equivalent, key selection criteria include falling-edge trigger polarity, retrigger capability, pulse width accuracy (±4.0% to ±6.4% depending on NDIV), DIV pin programmability for polarity and division ratio, and SOT-23 package compatibility with space-constrained industrial timing designs.
Technical Context
The LTC6993HS6-4#TRPBF implements a master oscillator with 1µs base period, controlled by ISET current sourced from the SET pin (regulated at 1.00V ±30mV). Pulse width tOUT = NDIV × RSET / 50kΩ × 1µs, where NDIV is selected via a 4-bit A/D converter on the DIV pin, supporting eight divider ratios (1, 8, 64, 512, 4096, 2¹⁵, 2¹⁸, 2²¹).
It features hysteresis on the TRIG pin (VTRIG_RISING ≈ 0.55×V+ + 185mV; VTRIG_FALLING ≈ 0.48×V+ – 155mV), fast propagation delay (11–28ns), and dynamic pulse width adjustment via control voltage on SET. The output is CMOS-compatible, sourcing/sinking up to ±20mA with rise/fall times under 2.7ns at 2.25V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pulse width range | 1µs to 33.6 seconds - supports ultra-low-frequency timing and high-resolution short pulses in one device |
| Trigger input | Falling-edge sensitive - initiates output on signal decay, ideal for edge-detection in noisy environments |
| Retrigger capability | Yes - extends active output pulse on successive falling edges, enabling adaptive timeout in watchdog or envelope tracking |
| Supply voltage | 2.25V to 5.5V - compatible with Li-ion, 3.3V, and 5V systems without level-shifting |

| SET (Pin 3) | Pulse width programming node | Sources 1.25µA–20µA current; voltage regulated at 1.00V ±30mV; connects to RSET for precision timing |
| DIV (Pin 4) | Divider ratio and polarity control | Voltage-programmed 4-bit A/D input; sets NDIV (1–2²¹) and output polarity (positive/negative pulse) |
| V+ (Pin 5) | Power supply input | 2.25V–5.5V single supply; requires 0.1µF ceramic bypass capacitor directly to GND |
| OUT (Pin 6) | CMOS output driver | Swings rail-to-rail (GND to V+); sources/sinks ±20mA; rise/fall time ≤2.7ns at 2.25V |
Key Features
| Feature | Design Value |

| Wide pulse width range (1µs–33.6s) | Single-component solution replaces discrete RC timers and microcontroller-based delays across multiple decades of timing |
| AEC-Q100 qualified (H-grade) | Validated for automotive under-hood use-supports functional safety requirements without additional qualification effort |
Applications
| Missing Pulse Detection | Envelope Detection |
|---|---|
Use Scenario: Monitoring periodic signals (e.g., engine crankshaft position) where absence of expected pulses indicates fault. IC Role / Device Role / Timing Role: Falling-edge retriggerable one-shot generating sustained logic-high output while pulses are present; output drops low after timeout if pulse is missed. Use Value: Detects signal loss within 1µs–33.6s window without software overhead-reduces MCU interrupt load and improves real-time response. | Use Scenario: Extracting amplitude envelope from modulated RF carriers (e.g., AM demodulation in sensor telemetry). IC Role / Device Role / Timing Role: Monostable triggered by carrier zero-crossings; output pulse width tracks modulation depth via RSET and DIV settings. Use Value: Achieves analog-like envelope reconstruction using only passive components and no op-amps-reduces BOM count and power in compact wireless nodes. |
| Watchdog Timer | High-Vibration Industrial Control |
Use Scenario: Supervising microcontroller health in industrial PLCs where firmware hang must reset system within strict time budget. IC Role / Device Role / Timing Role: Falling-edge input driven by MCU heartbeat signal; retriggerable behavior ensures reset only occurs after sustained failure. Use Value: Guarantees deterministic timeout (±4.0% accuracy) independent of MCU clock drift-enhances system reliability in safety-critical automation. | Use Scenario: Timing-critical sensing in heavy machinery subject to shock (>50g) and wide thermal swings (–40°C to 125°C). IC Role / Device Role / Timing Role: Provides stable pulse generation despite mechanical stress-induced PCB flexing and thermal cycling. Use Value: Maintains <±0.008%/°C pulse drift over full temperature range-avoids false triggers in vibration-sensitive proximity or safety interlock circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar monostable timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6993IS6-4#TRPBF | Same functionality and pinout; rated for –40°C to 85°C (I-grade) instead of –40°C to 125°C (H-grade) | Not suitable for under-hood automotive or high-temperature industrial enclosures | Select when ambient operating temperature remains below 85°C and cost sensitivity outweighs extended thermal margin |
| LTC6993HS6-2#TRPBF | Identical package, temperature rating, and supply range; rising-edge trigger (not falling-edge) and retriggerable | Requires inverted trigger signal or external inverter; unsuitable where falling-edge native detection is required | Choose only if system already generates rising-edge strobes and layout cannot accommodate signal inversion |
Compared with LTC6993IS6-4#TRPBF and LTC6993HS6-2#TRPBF, the LTC6993HS6-4#TRPBF uniquely combines automotive-grade temperature range with native falling-edge retriggering-enabling direct integration into vibration-prone sensor interfaces without signal conditioning or thermal derating.

FAQ
What is the trigger polarity and retrigger behavior of the LTC6993HS6-4#TRPBF?
The LTC6993HS6-4#TRPBF is a falling-edge-triggered, retriggerable monostable multivibrator. A falling transition on the TRIG pin initiates the output pulse, and subsequent falling edges occurring before pulse completion extend the output duration. This behavior is fixed per device variant and cannot be altered via configuration pins or registers.
How is pulse width programmed on the LTC6993HS6-4#TRPBF?
Pulse width on the LTC6993HS6-4#TRPBF is set by two independent controls: an external resistor (RSET) between SET and GND determines the master oscillator period, and a voltage divider on the DIV pin selects the division ratio (NDIV) and output polarity. The resulting tOUT = NDIV × RSET / 50kΩ × 1µs, with RSET ranging from 50kΩ to 800kΩ.
What is the operating temperature range and qualification status of the LTC6993HS6-4#TRPBF?
The LTC6993HS6-4#TRPBF is specified for –40°C to 125°C operation and is AEC-Q100 qualified for automotive applications. Its H-grade temperature rating and automotive qualification make it suitable for under-hood electronics, industrial motor controls, and other high-reliability environments where extended thermal stability is mandatory.
Can the LTC6993HS6-4#TRPBF generate both positive and negative output pulses?
Yes, the LTC6993HS6-4#TRPBF can generate either positive or negative output pulses. The polarity is determined by the MSB (POL bit) of the 4-bit DIVCODE value, which is set by the voltage applied to the DIV pin. When POL = 0, the output produces a positive pulse; when POL = 1, it produces a negative pulse-no external components are needed.
What are the supply current characteristics of the LTC6993HS6-4#TRPBF at minimum supply voltage?
At V+ = 2.25V with RSET = 800kΩ and NDIV ≥ 512, the LTC6993HS6-4#TRPBF draws only 55µA in idle state and 90µA in active state. This ultra-low quiescent current enables multi-year battery operation in remote monitoring devices and energy-harvesting applications without compromising timing accuracy.
