描述 Description

H-Bridge Driver IC

DW9800W is designed for linear control of bi-direction voice coil motors(Bi-VCM). DW9800W is a single 10-bit DAC with ±100mA output current sinking capability. DW9800W has Smart Actuator Control (SAC) mode. SAC mode can be applied to minimize the mechanical vibration. SAC mode has improved the actuator’s settling time and wide tolerance coverage compared with conventional Linear Slope Control (LSC) mode.
DW9800W also features an internal reference and operates from 2.3 V to 4.8V supply. DAC is controlled via I2C serial interface that operates at cloak rate up to 400kHz.
DW9800W has Power On Reset (POR) circuit mode. POR circuit gets to operate when supply voltage turns on. The output current keeps 0mA until valid register value takes place. DW9800W offers Power Down(PD) mode that ensure the minimal current (max. 2uA) is consumed in shutdown mode. DW9800W is protected by Thermal Shutdown (TSD) circuit for thermal shock.
