It is recommended that you should not exceed FAN5631/5632 or design them to their Absolute Maximum Ratings as stated to ensure optimal performance in the datasheet specifications. The recommended operating conditions are Vcc (supply voltage range) 2.2 to 5.5V, Iout (Output Current/Vin > 2V) max 250mA, and Ta (operating ambient temperature range) -40 to +85 C which typically +25 C.

The TDA5140A device is a bipolar integrated circuit which commonly used to draw 3-phase brushless DC motors in full-wave mode. This Brushless DC motor drive device is sensorless using the back-EMF sensing technique to sense the rotor position. This device used to be apply in applications such as VCR, laser beam printer, fax machine, blower, automotive. [...]

A: Apply momentary ground to reset hours to zero.
B: When using the MTH6 with inductive loads, we recommend installing a suppression diode across all coils.
C: Terminals 4 and 8 may be grounded on negative ground power supply.
D: Alternator must be equipped with a tach terminal (auxiliary AC terminal).
E: Connecting full battery potential to terminal 9 can cause damage
to the switchgage. Shutdown circuit is rated for 300 mA continuous. Circuit grounds out at set point. [...]

The laser driver circuit diagram shows the schematic of an IC-NZN application, an all-purpose laser driver circuit. It operates from 3.3 to 5.5 V and can drive N, M, and P-type laser diodes with or without monitor diode. The latest generation of all-purpose integrated laser driver solutions supports switching frequencies up to 155 MHz and laser currents up to 300 mA. [...]

The phase shift oscillator works in such a way that if the amplitude of the inverting amplifier is not high enough the system will continually attenuate the signal until the amplitude is zero, it was therefore decided to change the amplification power of the inverting amplifier. [...]
