Product details
Overview
LTC6993MPS6-2#TRPBF from Analog Devices is a retriggerable rising-edge monostable multivibrator (one-shot) IC with programmable pulse width from 1µs to 33.6 seconds, 2.25V–5.5V single-supply operation, and CMOS output capable of sourcing/sinking 20mA. It operates across –55°C to 125°C and is AEC-Q100 qualified for automotive watchdog and missing-pulse detection systems.
For engineers reviewing the LTC6993MPS6-2#TRPBF datasheet, LTC6993MPS6-2#TRPBF pinout, LTC6993MPS6-2#TRPBF application, or LTC6993MPS6-2#TRPBF equivalent, key selection criteria include retrigger capability, NDIV programmability via DIV pin voltage, RSET-based timing accuracy, and TSOT-23 package compatibility in high-vibration environments.
Technical Context
The LTC6993MPS6-2#TRPBF implements a master oscillator with 1µs base period, regulated VSET = 1.00V ±30mV, and an internal 4-bit A/D converter that maps DIV pin voltage to DIVCODE (0–15) to select NDIV (1, 8, 64, 512, 4096, 2¹⁵, 2¹⁸, 2²¹) and output polarity. Its rising-edge trigger logic supports retriggering with tRETRIG ≥ 10ns at V+ = 3.3V.
Timing accuracy depends on RSET tolerance and inherent ∆tOUT: ±2.3% for tOUT > 512µs, ±3.4% for 8µs–512µs, and ±4.9% for 1µs–8µs (NDIV = 1). Pulse width drift is ±0.006%/°C for NDIV ≥ 512 and ±0.008%/°C for NDIV ≤ 64 over full temperature range.
Key Specifications

Applications
| Watchdog Timer | Missing Pulse Detection |
|---|---|
Use Scenario: Monitors microcontroller activity in automotive ECUs to initiate safe shutdown if firmware hangs. IC Role / Device Role / Timing Role: Rising-edge retriggerable monostable that resets on each valid heartbeat signal; outputs low if no trigger within programmed window.

| Envelope Detection | High-Vibration Timing |
Use Scenario: Extracts amplitude envelope from RF carrier signals in battery-powered IoT transceivers. IC Role / Device Role / Timing Role: Generates gated sampling windows synchronized to carrier bursts using TRIG edge and programmable tOUT.

Equivalent & Alternatives
The following parts are listed as comparable options for similar monostable timing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC6993IS6-2#TRPBF | Same functionality and pinout; rated for –40°C to 85°C (not –55°C to 125°C) | Not qualified for extended-temperature automotive or military use | Select when industrial-grade temperature range suffices and cost optimization is prioritized |
| LTC6993HS6-2#TRPBF | Same functionality and pinout; rated for –40°C to 125°C (not –55°C) | Lacks MIL-STD-883 or AEC-Q100 MP-grade qualification for extreme cold start | Select for high-temp industrial applications where –55°C operation is unnecessary |

FAQ
What is the minimum pulse width achievable with LTC6993MPS6-2#TRPBF?
The LTC6993MPS6-2#TRPBF achieves a minimum output pulse width of 1µs when NDIV = 1 and RSET = 50kΩ. This is guaranteed across its full –55°C to 125°C operating range, with timing accuracy of ±4.9% for pulses between 1µs and 8µs. The 1µs capability enables high-speed digital debouncing and fast fault-response timing.
How does the retrigger function work on LTC6993MPS6-2#TRPBF?
The LTC6993MPS6-2#TRPBF is a rising-edge retriggerable monostable: each new TRIG rising edge while OUT is high resets the internal timer, extending the output pulse by tOUT from that trigger edge. Minimum inter-trigger spacing is 10ns at 3.3V supply. This behavior eliminates need for external retrigger logic in watchdog and pulse-stretch applications.
Can LTC6993MPS6-2#TRPBF generate negative output pulses?
Yes, the LTC6993MPS6-2#TRPBF can generate negative output pulses by programming the POL bit via the DIV pin voltage. When DIVCODE ≥ 8, POL = 1 and OUT goes low-active upon triggering. This is achieved using a resistor divider between V+ and GND on the DIV pin-no external inverter required. Polarity is set independently of NDIV selection.
What is the maximum RSET value supported by LTC6993MPS6-2#TRPBF?
The LTC6993MPS6-2#TRPBF supports RSET values up to 800kΩ, corresponding to ISET = 1.25µA at VSET = 1.00V. At this setting, tMASTER = 16µs and maximum tOUT reaches 33.6 seconds (NDIV = 2²¹). Using 800kΩ with 0.5% tolerance metal-film resistor ensures optimal timing accuracy and low temperature drift.
Is LTC6993MPS6-2#TRPBF compatible with 2.5V logic systems?
Yes, the LTC6993MPS6-2#TRPBF operates from 2.25V to 5.5V, making it fully compatible with 2.5V logic. At V+ = 2.5V, VOH = 2.17V (min) at –8mA and VOL = 0.26V (max) at 8mA, ensuring robust noise margins with standard 2.5V CMOS inputs. Supply current remains as low as 55µA in idle mode at 2.25V.
