Details Overview of Discrete Output H-Bridge Drive for Electrical Interface

H bridge drive. In addition to the specifications of the H-bridge driver given in Table B61, the parameters in Table B62 must be specified. Refer to Figure B37. Figure B37: Discrete output, H bridge. The protective elements D1 and C1 must be suitable and designed for protecting MOSFETs and MOSFET drivers, which are released due to overvoltage or overcurrent trigger in the closed state of sudden failure. Table B61: Discrete output, H bridge, electrical characteristics. parameter symbol Condition Note 1 lowest Typical value maximum unit Remark Uoh_min Highly effective state Tmin to Tmax, umin to umax. VS - 1 VS V In IOH_MAX UOL_MAX Low effective state Tmin to Tmax, umin to umax. 0 1.0 V In IOL_MAX Leakage current, not active Ioleak_max Maximum rated value 10 UA VS_PROT arrives at Signal_Gnd through the H-bridge.

Output frequency fly 0 25 KHZ Drive integrated load Need to protect The battery is short, grounded short. Allow protection Overcurrent and / or temperature is too high anti-static protect Note 2 Processing / drive KV Should meet GMW3097 Note 1: Umin, UNOM and UMAX are defined by the electrical code alphabet of the GMW3172 code string. Note 2: Input protection should via the GMW3097 verification requirements and include the A0805 size ceramic capacitor available on the connector plug.
