Product details
Overview
LTC6993MPS6-3#TRMPBF from Analog Devices is a monostable multivibrator (one-shot pulse generator) with programmable pulse width from 1µs to 33.6 seconds, falling-edge trigger input, non-retriggerable operation, and CMOS output sourcing/sinking ±20mA. It operates from 2.25V to 5.5V, consumes 70µA at 10µs pulse width, and is qualified for –55°C to 125°C industrial/military environments in TSOT-23 package.
For engineers reviewing the LTC6993MPS6-3#TRMPBF datasheet, LTC6993MPS6-3#TRMPBF pinout, LTC6993MPS6-3#TRMPBF application, or LTC6993MPS6-3#TRMPBF equivalent, key selection criteria include falling-edge trigger polarity, non-retriggerable timing behavior, wide temperature range (–55°C to 125°C), programmable NDIV divider (1 to 2²¹), and SET-pin resistor-based pulse width configuration.
Technical Context
The LTC6993MPS6-3#TRMPBF implements a master oscillator with 1µs base period controlled by ISET current sourced from the SET pin, where tMASTER = (RSET/50kΩ) × 1µs. Pulse width is determined as tOUT = NDIV × tMASTER, with NDIV selected via 4-bit DIVCODE derived from VDIV voltage on the DIV pin.
It features internal hysteresis on the TRIG pin (VTRIG(RISING) ≈ 0.55×V+ + 185mV; VTRIG(FALLING) ≈ 0.48×V+ – 155mV), fast 11–28ns propagation delay, and ±1.7% typical pulse width accuracy for NDIV ≥ 512. The device uses a digital filter and A/D converter to stabilize DIVCODE against noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pulse width range | 1µs to 33.6 seconds - supports ultra-short timing events and long-duration watchdog or delay functions without external RC networks. |
| Trigger input | Falling-edge sensitive - initiates output pulse on signal transition from high to low, enabling synchronization with falling logic edges or reset signals. |
| Retrigger capability | Non-retriggerable - ignores subsequent triggers until current pulse completes, ensuring deterministic one-shot behavior in noisy or multi-pulse environments. |
| Supply voltage | 2.25V to 5.5V - compatible with 3.3V and 5V systems, including battery-powered devices down to 2.25V brownout threshold. |
| Operating temperature | –55°C to 125°C - meets extended industrial and military requirements, validated across full range per MP-grade qualification. |
| Output drive | ±20mA CMOS - directly drives LEDs, MOSFET gates, or logic inputs without external buffers; rail-to-rail swing from GND to V+. |
| Pulse accuracy | ±2.3% (tOUT > 512µs), ±3.4% (8µs–512µs), ±4.9% (1µs–8µs) - enables precision timing in critical control loops and envelope detection circuits. |
Pinout & Package
Package: 6-Lead Plastic TSOT-23 (0.95mm × 2.9mm × 1.1mm height), lead-free, exposed pad optional, rated for –55°C to 125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TRIG (Pin 1) | Falling-edge trigger input | Initiates output pulse on falling transition; includes hysteresis for noise immunity; VIH/VIL thresholds scale with V+. |
| GND (Pin 2) | Analog/digital ground reference | Low-inductance return path for SET, TRIG, and output currents; must connect to solid ground plane. |
| SET (Pin 3) | Pulse width programming node | Sources ISET current (1.25µA–20µA); VSET regulated to 1.00V ±30mV; RSET between SET and GND sets tMASTER. |
| OUT (Pin 6) | CMOS output driver | Rail-to-rail switching output; sources/sinks ±20mA; requires series resistor when driving LEDs or low-Z loads. |
| V+ (Pin 5) | Power supply input | 2.25V–5.5V single supply; bypass with 0.1µF capacitor directly to GND pin for stable oscillator operation. |
| DIV (Pin 4) | Divider/polarity programming input | Accepts VDIV (0–V+) to select NDIV (1–2²¹) and output polarity (POL bit); max 100pF capacitance recommended. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pulse width | Configured via single RSET resistor and DIV pin voltage - eliminates need for multiple timing capacitors or complex digital controllers. |
| Falling-edge non-retriggerable trigger | Ensures single, unambiguous output pulse per valid falling edge - prevents false triggering in high-noise motor control or sensor interfaces. |
| Wide temperature operation | –55°C to 125°C guaranteed performance - suitable for under-hood automotive, aerospace, and industrial equipment without derating. |
| Low quiescent current | As low as 55µA at 2.25V/800kΩ RSET - extends battery life in portable instrumentation and remote sensors. |

Applications
| Watchdog Timer | Missing Pulse Detection |
|---|---|
Use Scenario: Monitors microcontroller activity in safety-critical systems (e.g., medical infusion pumps, avionics) by resetting on periodic falling-edge pulses. IC Role / Device Role / Timing Role: Falling-edge triggered monostable that asserts reset if pulse interval exceeds programmed tOUT. Use Value: Guarantees system recovery within 1µs–33.6s window; non-retriggerable behavior prevents spurious resets during transient faults. | Use Scenario: Detects failure of periodic signals in motor encoders or communication lines where missing clock edges indicate stall or break. IC Role / Device Role / Timing Role: Generates fault flag when falling-edge trigger stops arriving before tOUT expires. Use Value: Programmable timeout allows adaptation to varying base frequencies; operates reliably across –55°C to 125°C ambient. |
| Envelope Detection | High-Vibration Timing |
Use Scenario: Extracts amplitude envelope from modulated RF carriers (e.g., 80kHz ultrasound, IR remote signals) in portable diagnostic tools. IC Role / Device Role / Timing Role: Converts carrier zero-crossings into gated pulses whose width reflects modulation depth. Use Value: Sub-microsecond minimum pulse width enables accurate envelope capture at high carrier frequencies; low jitter (<0.85% P-P) preserves signal fidelity. | Use Scenario: Provides timing reference in shock/vibration-prone environments such as engine control units or drilling equipment. IC Role / Device Role / Timing Role: Generates stable delay or strobe pulses immune to mechanical stress-induced parameter drift. Use Value: ±0.006%/°C pulse width drift over temperature and <±0.1% supply sensitivity ensure consistent timing despite thermal cycling and voltage ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar monostable timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the trigger polarity and retrigger behavior of the LTC6993MPS6-3#TRMPBF?
The LTC6993MPS6-3#TRMPBF is a falling-edge triggered, non-retriggerable monostable. A falling transition on the TRIG pin initiates a single output pulse of programmable width; additional falling edges during the active pulse are ignored until completion and rearming. This behavior is fixed per the -3 variant and cannot be altered by external configuration.
How is pulse width programmed on the LTC6993MPS6-3#TRMPBF?
Pulse width on the LTC6993MPS6-3#TRMPBF is set using two independent controls: an RSET resistor from SET to GND determines the master oscillator period (tMASTER = RSET/50kΩ × 1µs), and the DIV pin voltage selects NDIV (1 to 2²¹) and output polarity. Final tOUT = NDIV × tMASTER. No external capacitor is required.
What is the operating temperature range certified for the LTC6993MPS6-3#TRMPBF?
The LTC6993MPS6-3#TRMPBF is MP-grade qualified for continuous operation from –55°C to 125°C, with full electrical specifications guaranteed across this range. This includes pulse width accuracy, supply current, and propagation delay - verified per Analog Devices' military-extended reliability testing protocols.
Can the LTC6993MPS6-3#TRMPBF generate both positive and negative output pulses?
Yes, the LTC6993MPS6-3#TRMPBF supports configurable output polarity via the DIV pin. When DIVCODE's MSB (POL bit) = 0, OUT goes high for the pulse duration; when POL = 1, OUT goes low. Polarity is selected by setting VDIV to one of 16 discrete voltages (e.g., 0.281×V+ for DIVCODE = 4), with ±1.5% tolerance allowed.
What package type and footprint does the LTC6993MPS6-3#TRMPBF use?
The LTC6993MPS6-3#TRMPBF uses a 6-lead Plastic TSOT-23 package (0.95mm × 2.9mm × 1.1mm height), identical to standard SOT-23-6 but with thinner profile. Pinout is TRIG–GND–SET–DIV–V+–OUT (top view), and the exposed pad is optional for thermal enhancement. Footprint matches JEDEC MO-178AC.
