■Features
•Lineup of built-in current sense resistor and
built-in protection circuit-type
•Power supply voltages, VBB: 46 V (max), 10 to
44 V normal operating range
•Logic supply voltages, VDD: 3.0 to 5.5 V
•Maximum output currents: 1 A, 1.5 A, 2 A, and
3 A
•Built-in sequencer
•Self-excitation PWM current control with fixed
off-time
•Synchronous PWM chopping function
prevents motor noise in Hold mode
•Sleep mode for reducing the IC input current
in stand-by state
•ZIP type 23-pin molded package (SLA
package)
*1: Output current value may be limited for the SLA7075MR, MPR (1.0 A), SLA7076MR, MPR (1.5 A), SLA7077MR, MPR
(2.0 A), and SA7078MR, MPR (3.0 A), depending on the duty ratio, ambient temperature, and heating conditions.
Do not exceed junction temperature of Tj under any circumstances.
