DIPIPM+ Series Application note

1.2 Functions

Inverter block
●For P-side IGBT
- Drive circuit
- High voltage level shift circuit
- Control supply under voltage (UV)
lockout circuit (without fault signal output)
- Built-in bootstrap diode (BSD)
with current limiting resistor
●For N-side IGBTs:
- Drive circuit;
- Short circuit (SC) protection circuit
- Control supply under voltage (UV)
lockout circuit (with fault signal output)
- Outputting LVIC temperature by analog signal
(No self over temperature protection)
(note) about SC protection
By detecting voltage of external shunt resistor,
DIPIPM+ works to protect.
●Fault signal output
- Corresponding to N-side IGBT SC protection
and N-side UV protection.
Brake block
●For IGBT
- Drive circuit
- UV protection circuit without fault signal
Common items
●IGBT drive supply
- Single DC15V power supply
●Control input supply
- High active logic with 5V
●UL recognized
- UL1557 File E323585

1.3 Applications

Motor drives for low power industrial equipment and commercial equipment such as air conditioners
