Key Features
- Voltage-controlled oscillator with programmable frequency range from 0.000488 MHz to 2 MHz set by a single external resistor, enabling simple frequency selection without crystals or ceramic resonators
- Automotive-grade silicon oscillator in a 6-pin TSOT-23 package (2.9 mm x 1.75 mm) with enable/disable pin for low-power shutdown and tape-and-reel packaging for automated assembly
- Part of the LTC6990 TimerBlox family with ±1.5% initial frequency accuracy and low jitter CMOS square wave output compatible with 1.8 V to 5.5 V logic systems
Applications
The LTC6990MPS6#TRPBF is used in automotive lighting control, industrial sensor timing, and power converter synchronization where a simple voltage-or-resistor-programmable clock source is needed without a microcontroller. Its wide frequency range covering sub-hertz to 2 MHz enables both low-frequency LED blink timers and moderate-speed PWM carrier generation from the same device family. The enable pin allows the oscillator to be gated by a system controller to reduce current consumption in duty-cycled or sleep-mode applications.

Frequently Asked Questions
What frequency range does the LTC6990MPS6#TRPBF cover, and how is the output frequency set?
The LTC6990MPS6#TRPBF produces a CMOS square wave from 0.000488 MHz (approximately 488 Hz) up to 2 MHz, with the output frequency programmed by selecting an external resistor value. A 4-to-1 divider pin extends the frequency range in octave steps, allowing the same resistor to generate 4 different frequencies by simply changing the DIV pin connection.
How does the LTC6990MPS6#TRPBF enable/disable function help reduce power in an automotive duty-cycled design?
The dedicated enable pin allows the oscillator to be switched off completely when the clock output is not required, reducing supply current to the shutdown level of approximately 0.5 µA. In an automotive body control module that only needs a clock during active measurement windows, gating the LTC6990MPS6#TRPBF from a microcontroller GPIO extends battery standby time and reduces quiescent current on the local power rail.
Why is the LTC6990MPS6#TRPBF's 6-pin TSOT-23 package and resistor-only programming preferable to a crystal oscillator module in a space-constrained automotive PCB?
The 6-pin TSOT-23 footprint measures only 2.9 mm x 1.75 mm x 1.0 mm, roughly 4 times smaller than a typical 3.2 mm x 2.5 mm crystal oscillator module. Setting frequency with one resistor instead of a crystal and two load capacitors reduces component count by 3 parts and eliminates the mechanical fragility and sensitivity to PCB stress that can shift a crystal's resonant frequency in automotive vibration environments.
For a 100 kHz PWM carrier generator in an industrial LED driver, how accurate is the LTC6990MPS6#TRPBF frequency output?
The LTC6990MPS6#TRPBF specifies ±1.5% initial frequency accuracy at a fixed temperature and supply voltage. At 100 kHz this corresponds to a frequency variation of ±1.5 kHz, which is acceptable for most PWM dimming applications where LED brightness is controlled by duty cycle rather than precise carrier frequency. If tighter accuracy is needed, an external voltage on the set resistor node can compensate for temperature drift across the -40 °C to +125 °C automotive range.
