Description

This COMBO driver for HDD application consists of sensorless spindle driver and BTL type VCM driver. “PWM soft switching function” for low power dissipation and less commutation acoustic noise at the same time is implemented by using the IPIC* process.

Features

• PWM soft switching drive• Small surface mount package: FP-48T

• Low thermal resistance: 30°C/W with 4 layer multi glass-epoxy board

• Low output on resistance

(1) Spindle 1.2 Ω Typ

(2) VCM 1.4 Ω Typ

• TTL compatible input level (with 3.3 V logic interface)

• High precision reference voltage output (for 3.3 V power supply
