• Built-in overcurrent protection (bus line) and pre-driver supply under voltage protection.
• Allows CMOS-level input of control signals without an insulating circuit.
•Use of an upper-side power supply bootstrap circuit (externally set) enables single power supply drive.
• Built-in circuit for preventing short circuits when both upper and lower inputs are ON at the same time.
This prevents arm short circuits due to simultaneous upper and lower phase ON inputs.
(A dead time is needed to prevent short circuits due to switching delay.)
• The level of the overcurrent protection current can be changed by using the external resistor RSDinserted between theISDand VSSterminals. (It is necessary to connect resistor RSDto assure normal operation of overcurrent protectionfunction. ISD is 28A to 38A when RSD is 0Ω.)
•The substrate temperature can be monitored through the use of an internal thermistor.
• Transfer full mold structure SIP. (Single Inline Package.)
