SA53-IHZ

SA53-IHZ Datasheet

The SA53 is a fully integrated switching amplifier designed primarily to drive DC brush motors. Two independent half bridges provide over 10 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 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 SA53 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.
