VNH5200AS-E：Automotive fully integrated H-bridge motor driver

The VNH5200AS-E is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches.

Both switches are designed using STMicroelectronics’ well known and proven proprietary VIPower^®M0 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry. The three dies are assembled in SO-16N package on electrically isolated leadframes. Moreover, its fully symmetrical mechanical design allows superior manufacturability at board level. The input signals IN_Aand IN_Bcan directly interface to the microcontroller to select the motor direction and the brake condition. The DIAG_A/EN_Aor DIAG_B/EN_B, when connected to an external pull-up resistor, enables one leg of the bridge. Each DIAG_A/EN_Aprovides a feedback digital diagnostic signal as well. The normal operating condition is explained in the truth table. The CS pin allows to monitor the motor current by delivering a current proportional to its value.
