Hoʻolālā ʻia no ka mana o ka pulse width modulated (PWM) o nā motika DC, hiki i ka A4950 ke hoʻokuʻu i nā kaha kiʻekiʻe i ka ± 3.5A a me ka hana ʻana i nā voltages a hiki i 40 V. Hāʻawi ʻia nā pahu hoʻokomo no ka hoʻohana ʻana i ka hoʻokele ʻana i ka wikiwiki a me ke kuhikuhi o kahi kaʻa DC me
hoʻohana ʻia i waho i nā hōʻailona mana PWM. Hāʻawi ʻia ka circuitry hoʻoponopono hoʻoponopono kūloko i ka hoʻohaʻahaʻa ʻana i ka mana i ka wā o ka hana PWM. Aia ka pale kaapuni kūloko i ka pale overcurrent, ke alakaʻi kaʻa pōkole i ka honua a i ʻole
lako, hoʻopaʻa wela me ka hysteresis, ka nānā ʻana i ka undervoltage o VBB, a me ka pale crossovercurrent. No nā noi ʻana o ka wela ambient kiʻekiʻe, hāʻawi ʻia kahi hāmeʻa kaʻa kaʻa (A4950K). Hoʻāʻo ʻia ka hāmeʻa papa K ma waena
ka lōʻihi o ka mahana a me ka volta e hōʻoia i ka hoʻokō ʻana i nā noi kaʻa a ʻoihana paha. Hāʻawi ʻia ka A4950 i loko o kahi pūʻolo SOICN 8-pin haʻahaʻa me ka pā wela i hōʻike ʻia (suffix LJ) ʻaʻole ke alakaʻi (Pb), me 100% matte tin.
