DESCRIPTION

The L6280 is a multipower driver system for motor and solenoid control applicatios that connects directly to a microprocessor bus. Realized in Multipower BCD technology -- which combines isolated DMOS transistors, CMOS & bipolar circuits on the same chip -- it integrates two 1A motor drivers (channels 1 & 2) a 3A solenoid driver (channel 3) and a 5V switchmode power supply.

■ PROGRAMMABLE CONFIGURATION (CHANNELS 1 AND 2)

■ OUTPUT CURRENT UP TO 1A (CHANNELS 1 AND 2)

■ 1 SENSE PER CHANNEL

■ OUTPUT CURRENT CHANNEL 3 UP TO 3A

■ DIRECT INTERFACE TO MICROPROCESSOR

■ C-MOS COMPATIBLE INPUT

■ INTERNAL DC-DC CONVERTER FOR LOGIC SUPPLY (+5V)

■ POWER FAIL

■ WATCHDOG MANAGEMENT

■ THERMAL PROTECTION

■ VERY LOW DISSIPATED POWER (SUITABLE FOR USE IN BATTERY SUPPLIED APPLICATIONS)
