SA306中文资料凌云逻辑数据手册PDF规格书

DESCRIPTION

The SA306 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. A block diagram is provided in Figure 1.

FEATURES

♦ Low cost 3 phase intelligent switching amplifier

♦ Directly connects to most embedded Microcontrollers and Digital Signal Controllers

♦ Integrated gate driver logic with dead-time generation and shoot-through prevention

♦ Wide power supply range (8.5V to 60V)

♦ Over 15A peak output current per phase

♦ 5A continuous output current per phase 8A continuous for A-Grade (SA306A)

♦ Independent current sensing for each output

♦ User programmable cycle-by-cycle current limit protection

♦ Over-current and over-temperature warning signals

APPLICATIONS

♦ 3 phase brushless DC motors

♦ Multiple DC brush motors

♦ 3 independent solenoid actuators
