500V 3-Phase Motor Driver ICs Rated from 1A to 3.5A

December 18, 2018 by Paul Shepard

The SLA6870MH and the SMA/SLA6860MH series from Sanken Electric are high voltage 3-phase motor driver ICs in which transistors, pre-driver ICs (MICs), and bootstrap circuits (diodes and resistors) are integrated.

These motor driver ICs are designed for use in a variety of consumer applications such as: fan motor and pump motor for washer and dryer; fan motor for air conditioner; and fan motor for air purifier and electric fan.

Selectable ZIP24 packages (fully-molded or heatsink type) with various leadforms enable optimal mounting for a wide range of applications. These products can optimally control the inverter systems of small- to medium-capacity motors.

The 4 fully-molded parts include: SMA6860MH 1A / 500V; SMA6862MH 1.5A / 500V; SMA6863MH and SMA6865MH both rated for 2.5A / 500V. The 2 heatsink-type devices include: SLA6868MH 2.5A / 500V; and SLA6870MH 3A / 500V.
