KA9258D

The KA9258D can be applicated in compact disk player (cdp), video compact disk player (VCD), automotive compact disk player, other compact disk media which is a monolithic integrated circuit, suitable for 4-CH motor driver which drives tracking actuator, focus actuator, sled motor and spindle motor of compack disk player system.

The features of KA9258D can be summarized as (1)4-CH balanced transformerless(BTL) driver; (2)output gain adjustable; (3)built in OP-amplifier; (4)built in mute function; (5)built in thermal shutdown circuit (TSD); (6)operating range 6 ~ 13.2V.

The absolute maximum ratings of KA9258D are (1)supply voltage VCC: 15 V; (2)power dissipation PD: 1.7 W; (3)operating temperature TOPR: -40 ~ +85 °C; (4)storage temperature TSTG: -55 ~ +150 °C; (5)maximum output current IOMAX: 1A(1. When mounted on 76.2mm × 114mm × 1.57mm PCB (Phenolic resin material). 2. Power dissipation reduces 13.6mW/°C for using above Ta=25°C 3. Do not exceed Pd and SOA (Safe Operating Area).).
