说明
DRV8833为玩具、打印机及其他机电一体化应用提供了一款双通道桥式电机驱动器解决方案。
该器件具有两个H桥驱动器,并能够驱动两个直流(DC)电刷电机、一个双极性步进电机、螺线管或其他电感性负载。
每个H桥的输出驱动器模块由N沟道功率MOSFET组成,这些MOSFET被配置成一个H桥,以驱动电机绕组。每个H桥都包括用于调节或限制绕组电流的电路。
借助正确的PCB设计,DRV8833的每个H桥能够连续提供高达1.5-A RMS(或DC)的驱动电流(在25℃和采用一个5V VM电源时)。每个H桥可支持高达2A的峰值电流。在较低的VM电压条件下,电流供应能力略有下降。
该器件提供了利用一个故障输出引脚实现的内部关断功能,用于:过流保护、短路保护、欠压闭锁和过热。另外,还提供了一种低功耗睡眠模式。
DRV8833内置于16引脚HTSSOP封装或采用PowerPAD™的QFN封装(绿环保:RoHS和无Sb/Br)。

(1)The junction-to-ambient thermal resistance under natural convection is obtained in a simulation on a JEDEC-standard,high-K board,as
specified in JESD51-7,in an environment described in JESD51-2a.
(2)The junction-to-case(top)thermal resistance is obtained by simulating a cold plate test on the package top.No specific
JEDEC-standard test exists,but a close description can be found in the ANSI SEMI standard G30-88.
(3)The junction-to-board thermal resistance is obtained by simulating in an environment with a ring cold plate fixture to control the PCB
temperature,as described in JESD51-8.
(4)The junction-to-top characterization parameter,ψJT,estimates the junction temperature of a device in a real system and is extracted
from the simulation data for obtainingθJA,using a procedure described in JESD51-2a(sections6and7).
(5)The junction-to-board characterization parameter,ψJB,estimates the junction temperature of a device in a real system and is extracted
from the simulation data for obtainingθJA,using a procedure described in JESD51-2a(sections6and7).
(6)The junction-to-case(bottom)thermal resistance is obtained by simulating a cold plate test on the exposed(power)pad.No specific
JEDEC standard test exists,but a close description can be found in the ANSI SEMI standard G30-88.
