Chip Introduction
The SS6952T provides a high current single channel integrated motor drive solution for integrated motor applications.
The SS6952T has an H-bridge drive that can provide a maximum peak current of 7A and drive a brush type DC motor, solenoid or other inductive loads. The power output module of SS6952T consists of H-bridge circuit composed of N-type Power MOSFET, including rectifier circuit and current limiting circuit. A simple parallel digital control interface with selectable attenuation modes for fast attenuation, slow attenuation, and mixed attenuation. The SS6952T provides a low-power sleep mode to turn off internal circuits to achieve very low quiescent current. This sleep mode is achieved by setting the nSLEEP pin. The internal shutdown function includes overcurrent protection, short circuit protection, Undervoltage-lockout protection and overtemperature protection, and provides a fault output pin nFAULT pin.
The SS6952T provides an eTSSOP28 package with exposed solder pads, which effectively improves heat dissipation performance and is a lead-free product. The pin frame is 100% Wuxi plated.
