Full Bridge DMOS PWM Motor Driver
Yopangidwira kuwongolera kwa pulse wide modulated (PWM) yamagetsi a DC, A4950 imatha kutulutsa mafunde apamwamba kwambiri mpaka ± 3.5A ndi ma voltages ogwiritsira ntchito mpaka 40 V. Malo olowera amaperekedwa kuti agwiritse ntchito kuwongolera liwiro ndi njira yagalimoto ya DC yokhala ndi
zizindikiro zowongolera za PWM zogwiritsidwa ntchito kunja. Internal synchronous rectification control circuitry imaperekedwa kuti ichepetse kutaya mphamvu panthawi ya PWM. Chitetezo chamkati chamkati chimaphatikizapo chitetezo cha overcurrent, motor lead yochepa mpaka pansi kapena
kupereka, kutseka kwamafuta ndi hysteresis, kuwunika kwa VBB, ndi chitetezo cha crossovercurrent. Pazogwiritsa ntchito kutentha kwambiri kozungulira, chipangizo chamtundu wamagalimoto chimaperekedwa (A4950K). Chipangizo cha K grade chimayesedwa kudutsa
kutentha kotalikirapo ndi ma voliyumu kuti zitsimikizire kutsatiridwa pamagalimoto kapena mafakitale. A4950 imaperekedwa mu phukusi la SOICN la 8-pini 8 yokhala ndi pad yotenthetsera (zokwanira LJ) zomwe zili ndi lead (Pb) zaulere, zokhala ndi malata 100% a matte.
leadframe plating
