SA306中文资料60V, 8A Low Cost PWM Brushless Motor Driver IC数据手册APEX规格书

描述 Description

The SA306A is a fully integrated switching amplifier designed primarily to drive three-phase Brushless DC (BLDC) motors. Three independent half bridges provide over 15 amperes peak output current under microcontroller or DSC control.

Thermal and short circuit monitoring is provided, which generates fault signals for the microcontroller to take appropriate action.

Additionally, cycle-by-cycle current limit offers user programmable hardware protection independent of the microcontroller. Output current is measured using an innovative low loss technique.

The SA306A is built using a multi-technology process allowing CMOS logic control and complementary DMOS output power devices on the same IC. Use of P-channel high side FETs enables 60V operation without bootstrap or charge pump circuitry.

The HSOP surface mount package balances excellent thermal performance with the advantages of a low profile surface mount package.
