General Description The LM621 is a bipolar IC designed for commutation of brushless DC motors. The part is compatible with both three- and four-phase motors. It can directly drive the power switching devices used to drive the motor. The LM621 provides an adjustable dead-time circuit to eliminate ``shootthrough'' current spiking in the power switching circuitry. Operation is from a 5V supply, but output swings of up to 40V are accommodated. The part is packaged in an 18-pin, dual-in-line package.

The MAX4968/MAX4968A are 16-channel, high-linearity,high-voltage, bidirectional SPST analog switches with18I (typ) on-resistance. The devices are ideal for use inapplications requiring high-voltage switching controlledby a low-voltage control signal, such as ultrasound imagingand printers. The MAX4968A provides integrated40kI (typ) bleed resistors on each switch terminal todischarge capacitive loads. Using HVCMOS technology,these switches combine high-voltage bilateral MOSswitches and low-power CMOS logic to provide efficientcontrol of high-voltage analog signals.

Recently a new technology for high voltage Power MOSFETshas been introduced – the CoolMOS™ . Based on thenew device concept of charge compensation the RDS(on) areaproduct for e.g. 600V transistors has been reduced by afactor of 5. The devices show no bipolar current contributionlike the well known tail current observed during the turn-offphase of IGBTs. CoolMOS™ virtually combines the lowswitching losses of a MOSFET with the on-state losses of anIGBT.
