#SCM1246MF Description
The SCM1246MF series are high voltage three-phase motor driver ICs in which transistors, pre-driver ICs (MICs), and bootstrap circuits (diodes and resistors) are highly integrated. These products can run on a three-shunt current detection system and optimally control the inverter systems of medium-capacity motors that require universal input standards.
Features
● Each half-bridge circuit consists of a pre-driver IC
● In case of malfunction, all outputs shut down via three FO pins connected together
● Built-in bootstrap diodes with current limmiting resistors (22 Ω)
● CMOS compatible input (3.3 to 5 V)
● Pb free
● Isolation voltage: 2500 V for 1 min,
UL recognized component (File No.: E118037)
● Fault signal output at protection activation
● Protections include:
Undervoltage Lockout for power supply
High-side (UVLO_VB): Auto-restart
Low-side (UVLO_VCC): Auto-restart
Overcurrent Protection (OCP): Auto-restart Simultaneous On-state Prevention: Auto-restart Thermal Shutdown (TSD): Auto-restart
