1 / 10 page 1/10 L6225 March 2001 This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change with out notice. s OPERATING SUPPLY VOLTAGE FROM 8 TO 52V s 2.8A PEAK CURRENT (1.4A DC) s RDS (ON) 0.73Ω TYP. VALUE @ Tj =25 °C s CROSS CONDUCTION PROTECTION s THERMAL SHUTDOWN s OPERATING FREQUENCY UP TO 100KHz s HIGH SIDE OVER CURRENT PROTECTION s CMOS/TTL INPUT s INTRINSIC FAST FREE WHEELING DIODES s UNDER VOLTAGE LOCKOUT TYPICAL APPLICATIONS s STEPPER MOTOR s DUAL OR QUAD DC MOTOR DESCRIPTION The L6225 is a dual full bridge driver for motor control applications manufactured with Multipower BCD technology which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The Logic Inputs are CMOS/TTL and µP compatible. The High Side switches are protected against unsafe over current conditions. Each full bridge is controlled by a separate Enable and has a sense pin for the current sense resistor in- sertion. Another feature is the thermal shutdown. The L6225 is assembled in PowerDIP20(16+2+2), PowerSO20 and SO20(16+2+2) packages. PowerDIP20 PowerSO20 SO20 (16+2+2) (16+2+2) ORDERING NUMBERS: L6225N L6225PD L6225D PRELIMINARY DATA DUAL DMOS FULL BRIDGE MOTOR DRIVER BLOCK DIAGRAM IN1B GND GND VSA VSA VSA Logic & Drivers VSB VSB VSB Charg e Pump GND VSA OUT2A VCP ENB IN1A IN2A SENSEA OUT1A GND VSB OUT2B VBOOT ENA IN2B SENSEB OUT1B |
