Product details
Overview
LTC6993HS6-1#TRPBF from Analog Devices is a rising-edge-triggered, non-retriggerable monostable multivibrator (one-shot) IC with programmable pulse width from 1µs to 33.6 seconds, 2.25V–5.5V single-supply operation, and –40°C to 125°C operating temperature range. It uses an external RSET resistor and DIV pin voltage to set timing and output polarity, and delivers CMOS-compatible 20mA-sourcing/sinking output.
For engineers reviewing the LTC6993HS6-1#TRPBF datasheet, LTC6993HS6-1#TRPBF pinout, LTC6993HS6-1#TRPBF application, or LTC6993HS6-1#TRPBF equivalent, key selection criteria include trigger edge polarity (rising), retrigger capability (none), pulse width accuracy (±4.9% at NDIV = 1), supply current (70µA at 10µs pulse), and TSOT-23 package compatibility with high-vibration environments.
Technical Context
The LTC6993HS6-1#TRPBF implements a master oscillator with 1µs base period, programmable via ISET current sourced from the SET pin (1.25µA–20µA), and a digitally controlled divider (NDIV = 1, 8, 64, ..., 2²¹) selected by a 4-bit A/D converter on the DIV pin. Its internal VSET regulation holds at 1.00V ±30mV, decoupling pulse width accuracy from supply variation when using RSET.
It features hysteresis on the TRIG input (VIH ≈ 0.7·V+, VIL ≈ 0.3·V+), fast propagation delay (11ns at 5.5V), and recovery time (tARM = –4ns), enabling robust timing in noisy industrial and automotive systems. The output stage provides rail-to-rail CMOS swing with 30Ω typical output resistance and 20mA drive capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pulse width range | 1µs to 33.6 seconds - supports ultra-short timing (e.g., digital pulse shaping) and long-duration events (e.g., watchdog timeout) |
| Trigger polarity | Rising-edge only - eliminates false triggering from slow or noisy falling edges in sensor interface applications |
| Retrigger capability | Non-retriggerable - ensures fixed-duration output regardless of repeated triggers during active pulse |
| Supply voltage | 2.25V to 5.5V - compatible with Li-ion, 3.3V, and 5V logic rails without level-shifting |
| Operating temp | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |
| Supply current | 70µA at 10µs pulse width (V+ = 2.25V, RSET = 800kΩ) - enables battery-powered envelope detection with multi-year runtime |
| Pulse accuracy | ±4.9% for 1µs–8µs pulses (NDIV = 1) - sufficient for missing-pulse detection and basic timing discrimination |
Pinout & Package
Package: 6-Lead Plastic TSOT-23 (0.95mm height), RoHS-compliant, lead-free finish. Exposed pad not present. Compatible with standard SMT reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TRIG (Pin 1) | Asynchronous trigger input | Rising-edge sensitive; internal hysteresis (VIH/VIL proportional to V+) rejects noise and accommodates slow signals |
| GND (Pin 2) | Analog/digital reference | Low-inductance ground plane connection required; shares return path for SET, DIV, and OUT |
| SET (Pin 3) | Pulse width programming node | Sources ISET (1.25–20µA); regulated VSET = 1.00V ±30mV; ≤10pF capacitance required for low jitter |
| OUT (Pin 6) | CMOS output driver | Rail-to-rail swing (GND to V+); 20mA sourcing/sinking; 30Ω typical output impedance; requires series resistor for LED/low-Z loads |
| V+ (Pin 5) | Power supply | 2.25V–5.5V operation; bypass with 0.1µF ceramic capacitor directly to GND pin |
| DIV (Pin 4) | Divider ratio & polarity control | 4-bit A/D input; sets NDIV (1–2²¹) and POL bit (output polarity); ≤100pF capacitance; driven by resistor divider |
Key Features
| Feature | Design Value |
|---|---|
| Programmable pulse width | 1µs–33.6s via single RSET resistor and DIV pin voltage - eliminates need for external counters or microcontrollers |
| Wide supply range | 2.25V–5.5V operation - supports direct integration into mixed-voltage systems without regulators |
| High-temp operation | –40°C to 125°C guaranteed performance - suitable for engine control units and power inverters |
| Low quiescent current | 70µA idle current at 2.25V - extends battery life in portable envelope detectors and pulse monitors |
| CMOS output drive | 20mA sourcing/sinking with rail-to-rail swing - directly interfaces with logic gates, MOSFET gates, and optocouplers |

FAQ
What is the minimum pulse width supported by the LTC6993HS6-1#TRPBF?
The LTC6993HS6-1#TRPBF supports a minimum output pulse width of 1µs when configured with NDIV = 1 and RSET = 50kΩ. This value is guaranteed over the full –40°C to 125°C operating temperature range and is validated per the electrical characteristics table in the Rev. F datasheet.
Does the LTC6993HS6-1#TRPBF require external passive components to operate?
Yes, the LTC6993HS6-1#TRPBF requires at minimum an RSET resistor between SET and GND to program pulse width, and a 0.1µF ceramic bypass capacitor between V+ and GND. Optional resistors on the DIV pin configure NDIV and output polarity. No external timing capacitors or crystals are needed.
Can the LTC6993HS6-1#TRPBF be used in automotive applications?
Yes, the LTC6993HS6-1#TRPBF is specified for –40°C to 125°C operation and is AEC-Q100 qualified for automotive applications. Its TSOT-23 package, low supply current, and robust trigger hysteresis make it suitable for engine control, body electronics, and ADAS subsystems.
How does the DIV pin determine output polarity on the LTC6993HS6-1#TRPBF?
The DIV pin voltage is converted to a 4-bit DIVCODE by an internal A/D converter. The MSB (POL bit) of DIVCODE controls output polarity: POL = 0 produces a positive pulse (LOW→HIGH→LOW), POL = 1 produces a negative pulse (HIGH→LOW→HIGH). Table 1 in the datasheet maps resistor pairs to specific POL and NDIV values.
What is the maximum load the LTC6993HS6-1#TRPBF output can drive?
The LTC6993HS6-1#TRPBF output can source or sink up to ±20mA while maintaining VOH ≥ 2.17V and VOL ≤ 0.26V at V+ = 2.25V. For loads exceeding this (e.g., LEDs or MOSFET gates), a series current-limiting resistor is required to prevent exceeding the 20mA absolute maximum rating.
