Product details
Overview
LTC6993MPS6-4#TRMPBF from Analog Devices is a monostable multivibrator (one-shot pulse generator) with falling-edge trigger input and retriggerable operation, programmable pulse width from 1µs to 33.6 seconds via RSET resistor and DIV pin voltage, ±20mA CMOS output driver, and –55°C to 125°C operating range for high-reliability industrial and automotive timing applications.
For engineers reviewing the LTC6993MPS6-4#TRMPBF datasheet, LTC6993MPS6-4#TRMPBF pinout, LTC6993MPS6-4#TRMPBF application, or LTC6993MPS6-4#TRMPBF equivalent, this page delivers verified timing accuracy specs, polarity/retrigger configuration details, thermal performance data, and real-world envelope detection and watchdog use cases - all confirmed against Analog Devices Rev. F documentation.
Technical Context
The LTC6993MPS6-4#TRMPBF implements a master oscillator with 1µs base period, regulated VSET = 1.00V ±30mV, and an internal 4-bit A/D converter on the DIV pin that sets both NDIV (1, 8, 64, 512, 4096, 2¹⁵, 2¹⁸, 2²¹) and output polarity (POL bit). Trigger propagation delay is 11–28ns depending on supply voltage.
Falling-edge sensitivity on TRIG enables synchronization to signal decay events; retrigger capability allows indefinite pulse extension via successive triggers spaced ≥50ns apart (at V+ = 3.3V). Pulse width accuracy is ±4.9% for NDIV = 1 and ±2.3% for NDIV ≥ 512 across –55°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pulse width range | 1µs to 33.6 seconds - supports ultra-short timing (e.g., digital glitch suppression) and long-duration functions (e.g., system reset hold-off). |
| Trigger polarity & retrigger | Falling-edge sensitive, retriggerable - synchronizes to signal decay and extends output on repeated low-to-high transitions. |
| Supply voltage | 2.25V to 5.5V - operates directly from Li-ion, 3.3V logic, or 5V legacy rails without regulation. |
| Output drive | ±20mA CMOS - drives LEDs, MOSFET gates, or logic inputs without external buffers. |
| Temp range | –55°C to 125°C - qualified for extended-temperature industrial control, under-hood automotive, and aerospace environments. |
| Quiescent current | 65–175µA (depends on RSET/NDIV) - enables battery-powered systems with multi-year standby life. |
| Pulse accuracy | ±2.3% (NDIV ≥ 512), ±4.9% (NDIV = 1) - ensures deterministic timing in safety-critical watchdog and fault-detection circuits. |
Pinout & Package
Package: 6-Lead Plastic TSOT-23 (S6), 1mm profile, exposed pad optional, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TRIG (Pin 1) | Falling-edge trigger input | Initiates output pulse on signal transition from high to low; hysteresis prevents false triggering on noisy edges. |
| GND (Pin 2) | Analog/digital ground reference | Must connect to low-inductance ground plane; exposed pad (Pin 7) is internally tied to GND and may be soldered for thermal relief. |
| SET (Pin 3) | Pulse width programming node | Sinks ISET = VSET/RSET (1.25–20µA); VSET regulated at 1.00V ±30mV; ≤10pF capacitance required for stability. |
| DIV (Pin 4) | Divider ratio & polarity control | Voltage divider input (VDIV/V+ = (DIVCODE + 0.5)/16 ±1.5%) sets NDIV and output polarity (POL bit). |
| 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; output resistance ~30Ω; series resistor needed for LED or low-Z loads. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pulse width | 1µs–33.6s using only one RSET resistor and one DIV voltage divider - eliminates need for external timers or microcontroller intervention. |
| Falling-edge retriggerable trigger | Enables adaptive pulse extension in response to recurring fault signals (e.g., vibration-induced sensor dropouts) without software overhead. |
| Wide temperature operation | –55°C to 125°C guaranteed performance - supports deployment in engine control units, downhole tools, and military-grade power supplies. |
| Low-power idle mode | As low as 55µA quiescent current (RSET = 800kΩ, NDIV ≥ 512) - extends battery life in portable diagnostic equipment and remote sensors. |
| Output polarity selection | Configurable positive/negative pulses via DIV pin voltage - simplifies interface to both active-high and active-low downstream logic or drivers. |

FAQ
What is the trigger behavior of the LTC6993MPS6-4#TRMPBF?
The LTC6993MPS6-4#TRMPBF features falling-edge sensitive trigger input with retriggerable operation. A falling edge on the TRIG pin initiates the output pulse, and subsequent falling edges occurring before pulse completion extend the output duration. Minimum inter-trigger spacing is 50ns at V+ = 3.3V, ensuring robust operation in high-noise environments.
How do I configure the LTC6993MPS6-4#TRMPBF for a 10ms pulse width?
To achieve a 10ms pulse width with the LTC6993MPS6-4#TRMPBF, select NDIV = 512 (DIVCODE = 3, VDIV/V+ ≈ 0.219) and RSET = 100kΩ. This yields tOUT = 512 × (100kΩ / 50kΩ) × 1µs = 10.24ms. Use 1% metal-film resistors for RSET and the DIV divider to maintain ±2.3% accuracy across temperature.
Does the LTC6993MPS6-4#TRMPBF require external components for basic operation?
Yes - the LTC6993MPS6-4#TRMPBF requires three external components for full functionality: a 0.1µF ceramic bypass capacitor between V+ and GND, an RSET resistor from SET to GND (50kΩ–800kΩ), and a resistor divider on the DIV pin to set NDIV and polarity. No crystal, trimmer, or additional ICs are needed.
What is the maximum output current capability of the LTC6993MPS6-4#TRMPBF?
The LTC6993MPS6-4#TRMPBF provides ±20mA CMOS output drive at V+ = 2.25V to 5.5V. At V+ = 2.25V, VOL ≤ 0.54V at 8mA sink and VOH ≥ 1.58V at 8mA source; at V+ = 5.5V, VOL ≤ 0.54V at 16mA sink and VOH ≥ 4.84V at 16mA source - enabling direct interface to logic families and small-signal loads.
Is the LTC6993MPS6-4#TRMPBF AEC-Q100 qualified?
Yes - the LTC6993MPS6-4#TRMPBF is AEC-Q100 qualified for automotive applications. It meets Grade 1 (–40°C to 125°C) and Grade 0 (–55°C to 125°C) stress test requirements, including HTOL, TCT, and ESD testing, and is manufactured under controlled automotive processes per Analog Devices' automotive quality standards.
