SA5901
4-CHANNEL MOTOR DRIVER FOR PORTABLE CD PLAYER
DESCRIPTION
SA5901 is suitable for portable CD player with 4-ch H bridge drivers and DC/DC converter control circuit. Because of the small package QFP44, it is most suitable for small equipment.
QFP44-10 x10-0.8
FEATURES
∗ Four channels of H-bridge drivers are contained. ∗ DC/DC converter control circuit is contained. ∗ Reset circuit ∗ Reduced voltage detection circuit. ∗ Battery charging circuit ∗ General purpose operational amplifier is contained ∗ Low power consumption ∗ Thermal shutdown circuit ∗ QFP-44 package ∗ Load drive voltage can be processed by PWM control through an external component. ∗ Excellent gain can be obtained by a voltage feedback circuit. ∗ Mute function is disabled for ch1, ch2 and ch3/ch4 respectively. ∗ Starter and power off function ∗ Soft-start function and short-circuit protection function ∗ Self-advancing oscillation and clock synchronization are available. ∗ Reset voltage is interlocked with the set voltage of DC/DC converter. ∗ Inversion output pin for reset output is available. ∗ Battery charger and dry battery allow to switch “ Empty” detection level.
