Product details
Overview
LTC6993MPS6-1#TRPBF from Analog Devices is a monostable multivibrator (one-shot pulse generator) with programmable pulse width from 1µs to 33.6 seconds, rising-edge non-retriggerable trigger input, 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 and automotive environments.
For engineers reviewing the LTC6993MPS6-1#TRPBF datasheet, LTC6993MPS6-1#TRPBF pinout, LTC6993MPS6-1#TRPBF application, or LTC6993MPS6-1#TRPBF equivalent, key selection criteria include pulse width accuracy (<2.3% for >512µs), retrigger capability (none), trigger polarity (rising-edge), output polarity configurability, and TSOT-23 package compatibility with high-vibration systems.
Technical Context
The LTC6993MPS6-1#TRPBF implements a master oscillator with 1µs base period, programmable via SET pin current (ISET = VSET/RSET), and an internal 4-bit A/D converter on the DIV pin that selects both NDIV (1, 8, 64, ..., 2²¹) and output polarity (POL bit). Its timing architecture ensures pulse width independence from supply voltage drift when using RSET.
It features hysteresis on the TRIG pin (VIH ≈ 0.7·V+, VIL ≈ 0.3·V+), fast propagation delay (11ns at 5.5V), and guaranteed operation across –55°C to 125°C with AEC-Q100 qualification. The device halts oscillation if ISET falls below ~500nA, enabling low-power timeout detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pulse width range | 1µs to 33.6 seconds - supports ultra-short timing events and long-duration timeouts without external RC networks. |
| Pulse width accuracy | ±2.3% (typ) for tOUT > 512µs - enables reliable timing in watchdog and missing-pulse detection circuits. |
| Supply voltage | 2.25V to 5.5V - compatible with Li-ion, 3.3V, and 5V logic rails without level-shifting. |
| Supply current | 70µA at 10µs pulse width, V+ = 2.25V - extends battery life in portable equipment. |
| Operating temperature | –55°C to 125°C - validated for under-hood automotive and industrial control applications. |
| Output drive | ±20mA CMOS - directly drives LEDs, MOSFET gates, or logic inputs without buffering. |
| Trigger type | Rising-edge, non-retriggerable - prevents false triggering during noisy transients; ignores subsequent edges until pulse completes. |
Pinout & Package
Package: 6-Lead Plastic TSOT-23 (0.95mm height), RoHS-compliant, lead-free finish. Exposed pad not present in S6 package.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TRIG (Pin 1) | Trigger input | Rising-edge sensitive; initiates output pulse; includes hysteresis for noise immunity on slow signals. |
| GND (Pin 2) | Ground reference | Low-inductance return path for all internal circuitry; must connect to solid ground plane. |
| SET (Pin 3) | Pulse width programming | Sinks current (1.25µA–20µA); connects to precision resistor to GND for accurate tOUT setting. |
| OUT (Pin 4) | Output driver | CMOS rail-to-rail output; sources/sinks 20mA; swing from GND to V+ with ~30Ω impedance. |
| V+ (Pin 5) | Power supply | 2.25V–5.5V input; requires local 0.1µF ceramic bypass capacitor to GND. |
| DIV (Pin 6) | Divider & polarity control | 4-bit A/D input; sets NDIV and POL via resistor divider; VDIV/V+ ratio must be within ±1.5% of ideal. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pulse width | 1µs–33.6s via single RSET resistor and DIV pin voltage - eliminates need for discrete timers or microcontroller intervention. |
| Rising-edge non-retriggerable operation | Guaranteed one-shot behavior: ignores additional triggers until output completes and re-arms - critical for fault-limited safety sequencing. |
| Wide temperature range | –55°C to 125°C operation with full parameter guarantee - suitable for engine control units and downhole instrumentation. |
| Low quiescent current | 65–70µA typical at 2.25V supply - enables multi-year battery life in remote sensor nodes. |
| Configurable output polarity | POL bit set via DIVCODE allows positive or negative output pulses - simplifies interface with downstream logic or analog comparators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar monostable timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6993IS6-1#TRPBF | Same functionality and pinout; rated for –40°C to 85°C instead of –55°C to 125°C. | Not qualified for extended cold-start or under-hood automotive use. | Select when ambient operating temperature remains above –40°C and AEC-Q100 is not required. |
| LTC6993HS6-1#TRPBF | Same functionality and pinout; rated for –40°C to 125°C (not –55°C); no MP-grade qualification. | Lacks military/extended-temperature validation; may not meet automotive reliability reporting requirements. | Select for industrial high-temp applications where –55°C start-up is unnecessary and cost sensitivity exists. |

FAQ
What is the trigger behavior of LTC6993MPS6-1#TRPBF?
LTC6993MPS6-1#TRPBF responds exclusively to rising-edge transitions on the TRIG pin and is non-retriggerable: once the output pulse begins, subsequent rising edges are ignored until the pulse completes and the internal rearm timer expires. This ensures deterministic one-shot operation critical for safety-critical timing.
How is pulse width programmed on LTC6993MPS6-1#TRPBF?
Pulse width on LTC6993MPS6-1#TRPBF is set by two independent controls: a resistor (RSET) between SET and GND determines the master oscillator period (tMASTER = 1µs × RSET/50kΩ), and the DIV pin voltage selects NDIV (1 to 2²¹) and output polarity. Final tOUT = NDIV × tMASTER.
Does LTC6993MPS6-1#TRPBF require external components for basic operation?
Yes - LTC6993MPS6-1#TRPBF requires at minimum a 0.1µF ceramic capacitor from V+ to GND, a precision resistor (50kΩ–800kΩ) from SET to GND, and a resistor divider on the DIV pin to select NDIV and polarity. No external timing capacitors or crystals are needed.
What is the maximum output current capability of LTC6993MPS6-1#TRPBF?
LTC6993MPS6-1#TRPBF provides rail-to-rail CMOS output with guaranteed ±20mA drive strength at V+ = 2.7V to 5.5V. VOH ≥ 4.84V and VOL ≤ 0.26V at 16mA sink/source load, enabling direct interface with logic gates, LEDs, or MOSFET drivers without external buffers.
Is LTC6993MPS6-1#TRPBF qualified for automotive applications?
Yes - LTC6993MPS6-1#TRPBF is AEC-Q100 qualified and specified for –55°C to 125°C operation. It meets automotive reliability standards including HTOL, TCT, and ESD testing, and is designated for use in engine control, transmission, and ADAS subsystems where extended temperature and robustness are mandatory.
