SD5888S

Overview

SD5888S is a five-channel BTL driver circuit, mainly used for DVD playback The drive of the machine servo motor and the servo coil also contains two independent precision voltage regulators with an adjustable range of 1.5V ~ 4V. Supports different application scenarios. Function: · Two-channel voltage type BTL driver for focusing and tracing coil; two-channel voltage type BTL driver for spindle and sliding motor; also built-in one-channel in/out box bidirectional DC motor driver. · Wide dynamic range: [9.0V (typical) when Vcc1 = Vcc2 = 12V, load RL = 20Ω]. · Vcc1 and Vcc2 power supplies are independent of each other · Built-in level transfer circuit · Built-in thermal protection circuit · Built-in Quiet Mode Circuit · Dual coil drive and sliding motor drive: Different signal addition inputs are provided by the general operational amplifier, and the output structure is a two-power OPAMPS bridge structure. · Spindle drive: Independent linear BTL driver input, output structure is two-power OPAMPS bridge structure. · Access Box Drive: DC motor drive provides positive/negative phase control of the motor · Two built-in voltage regulators: Adjustable range: 1.5V~4V
