TB9058FNG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB9058FNG Automotive DC Servo Motor Driver 1. Description TB9058FNG is an automotive DC servo motor driver. With a target motor rotational position supplied by the external LIN (Local Interconnect Network) signal, it measures the current motor position using a potentiometer and controls motor rotation so that its rotational position reaches to the target position. Up to 16 devices can be connected as slaves on a single bus. Weight: 0.13 g (typ.) 2. Applications Automotive DC Servo Motor Driver 3. Features Data communications with LIN (slave) Communication rate: 19,200 / 9,600 / 4,800 / 2,400 bps (with switching pins) Based on LIN 1.3 Protocol Specification Enhanced Checksum Bidirectional DC motor driver(H-bridge): 1 channel (R typ.: Pch+Nch = 2.2 ) on Driver short-circuit protection: 1.5 A (typ.)
