... When compared against industry-standard 555-timer- based products, the TS3001 offers up to 93% reduction in pcb area and four orders of magnitude lower power consumption. The TS3001 is fully specified over the -40°C to +85°C temperature range and is available in a low-profile, 8- pin 2x2mm TDFN package with an exposed back- side paddle. ...

... Note 2: Output rise and fall times are measured between the 10% and 90% of the V on lab bench characterization and is not tested in production. Note 3: Timing jitter is the ratio of the peak-to-peak variation of the period to the mean of the period. The specification is based on lab bench characterization and is not tested in production.

... Ground – Connect this pin to the system’s analog ground plane. FOUT Programming Resistor Input. A 4.32MΩ resistor connected from this pin to GND sets the TS3001’s internal oscillator’s output period to 40μs (25kHz). For optimal performance, the composition of the RSET resistor shall be consistent with tolerances lower ...

... VDD increases the duty cycle to 90% and connecting CNTRL to VDD disables the PWM engine altogether. Configured for nominal operation (PWM engine OFF), the supply current of the TS3001 is 1µA; enabling the PWM engine increases the TS3001 operating supply current as shown in the electrical specification table ...

... Potentiometer to Trim the T 3001’s Output Frequency. TS3001DS r1p0 Using Standard Resistors to Increase FOUT Resolution The TS3001 can be configured to provide a 0.1% resolution on the output frequency as shown in Figure so, R1 can be set to approximately 10% of the value selected for R2. In addition, R2 and R1 should be chosen with a 0.1% and 1% tolerance, respectively ...
