Com 2 MAXIMUM RATINGS Rating Symbol Value Unit Power Supply Voltage VCC + 36 or ± 18 V Input Differential Voltage VIDR 36 V Input Common Mode Voltage Range VICR − 0. The LM193/ LM193A/ LM293 must be derated based on a 150˚ C maximum junction temperature. TI lm393 の LM393- N データシート. Edit: I forgot to add, the diode is to protect the transistor from the high voltage spike that' datasheet s generated when the relay switches off. The circuit is great for controlling the power delivered to a device such as a fan LED’ s , even transformers lm393 coils. If your relay uses comfortably under 100mA, you could use a BC548 transistor. This device uses a built in pulse width modulated signal generator circuit for triggering a power MOSFET.
The gate of the mosfet is in reality and capacitor. The Lm393 has an Open Collector output so it cannot supply a Positive output so the resistor is there to switch on the transistor. or a transistor between the output of the LM393 and the mosfet gate.

Due to the PNP transistor inputs, bias current will flow out of the inputs. IN+ the offset voltage, the output is low the output transistor is sinking. A DIY Power Pulse Controller.

My problem is " how fast can an LM393 drive the gate of a small MOSFET"? At the moment the exact type of MOSFET isn' t finalised, and even if it was I' ve yet to see a datasheet give a straight answer on the actual value of gate capacitance, if I knew that I could calculate the charge/ discharge time with the minimum allowable 393 O/ P pull up resistor.
