Product details
Overview
LTC6993MPS6-4#TRPBF from Analog Devices is a monostable multivibrator (one-shot pulse generator) with falling-edge trigger input, retriggerable operation, and programmable pulse width from 1µs to 33.6 seconds. It uses a single RSET resistor and DIV pin voltage to configure NDIV divider (1–221) and output polarity, delivering ±20mA CMOS output drive across –55°C to 125°C. It serves in missing-pulse detection and high-vibration watchdog timing.
For engineers reviewing the LTC6993MPS6-4#TRPBF datasheet, LTC6993MPS6-4#TRPBF pinout, LTC6993MPS6-4#TRPBF application, or LTC6993MPS6-4#TRPBF equivalent, key selection criteria include falling-edge retrigger capability, 6-pin TSOT-23 package, ±2.3% pulse width accuracy for >512µs pulses, 70µA supply current at 10µs pulse width, and AEC-Q100-qualified temperature range.
Technical Context
The LTC6993MPS6-4#TRPBF implements a master oscillator with 1µs minimum period, regulated VSET = 1V ±30mV, and internal 4-bit A/D converter for DIVCODE interpretation. Its falling-edge sensitive TRIG input enables retriggering, extending output pulse duration on successive valid triggers spaced ≥50ns apart at 3.3V.
Pulse width tOUT = NDIV × RSET / 50kΩ × 1µs is determined by RSET (50kΩ–800kΩ) and DIVCODE-selected NDIV (1, 8, 64, 512, 4096, 2¹⁵, 2¹⁸, 2²¹), with POL bit setting output polarity. The device features hysteresis on TRIG (VTRIG_RISING ≈ 0.55×V+ + 185mV; VTRIG_FALLING ≈ 0.48×V+ – 155mV) and 500µs startup time.

FAQ
What is the trigger polarity and retrigger behavior of the LTC6993MPS6-4#TRPBF?
The LTC6993MPS6-4#TRPBF features a falling-edge sensitive TRIG input and is retriggerable-each valid falling edge extends the output pulse width by tOUT from that trigger point. Minimum inter-trigger spacing is 50ns at 3.3V supply. This behavior enables dynamic pulse shaping in envelope detection and burst-mode signal conditioning without processor involvement. The LTC6993MPS6-4#TRPBF maintains this function across its full –55°C to 125°C operating range.
How is pulse width programmed on the LTC6993MPS6-4#TRPBF?
Pulse width on the LTC6993MPS6-4#TRPBF is set using two independent controls: an RSET resistor from SET to GND (50kΩ–800kΩ) defines the master oscillator period, while the DIV pin voltage selects NDIV (1–221) and output polarity via a 4-bit A/D converter. The resulting tOUT = NDIV × RSET / 50kΩ × 1µs equation allows precise, resistor-based timing without trimming or calibration. The LTC6993MPS6-4#TRPBF achieves ±2.3% accuracy for pulses >512µs using standard 1% resistors.
What is the operating temperature range and qualification status of the LTC6993MPS6-4#TRPBF?
The LTC6993MPS6-4#TRPBF is specified for continuous operation from –55°C to 125°C and is AEC-Q100 qualified for automotive applications. This qualification includes stress testing per Grade 1 (–40°C to 125°C) plus extended low-temperature validation down to –55°C. Unlike commercial or industrial variants, the LTC6993MPS6-4#TRPBF guarantees full electrical performance-including pulse width accuracy, supply current, and propagation delay-across this extended range. The LTC6993MPS6-4#TRPBF is therefore suitable for engine control, transmission, and ADAS modules requiring cold-cranking reliability.
Can the LTC6993MPS6-4#TRPBF generate both positive and negative output pulses?
Yes, the LTC6993MPS6-4#TRPBF supports configurable output polarity via the DIV pin voltage. When DIVCODE's MSB (POL bit) = 0, the OUT pin produces a positive pulse (low-to-high transition); when POL = 1, it produces a negative pulse (high-to-low). This is selected by setting VDIV/V+ to one of 16 defined ratios (e.g., 0.28125 for DIVCODE = 4, 0.71875 for DIVCODE = 11), achievable with matched 1% resistors. No external inverter is needed, simplifying PCB layout and reducing component count in mixed-signal timing designs using the LTC6993MPS6-4#TRPBF.
What are the power supply requirements and quiescent current of the LTC6993MPS6-4#TRPBF?
The LTC6993MPS6-4#TRPBF operates from a single 2.25V to 5.5V supply, with absolute maximum rating of 6V. At 2.25V supply and RSET = 800kΩ, quiescent current is 55µA (typical); at 5.5V and same conditions, it is 65µA. For a 10µs pulse width, supply current is 70µA (typical) - enabling multi-year battery life in always-on sensor nodes. The LTC6993MPS6-4#TRPBF includes internal power-on reset and requires a 0.1µF ceramic capacitor from V+ to GND placed near the package for stable operation.
