Because the current clamp is applied to the top H-bridge transistors only, overcurrent protection applies to motor currents. But note that no short circuit protection exists against shorts from the DC motor outputs (DR1A1, DR1A2, DR1B1, or DR1B2 to substrate ground or to VB+. Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 21 V ≤ VVB+ ≤ 42 V, TA = 10°C to 55°C, TJ max = 135°C, VCC = 5.25 V max unless otherwise noted. Typical values noted reflect the approximate parameter mean at TA = 25°C under typical conditions unless otherwise noted. Characteristic Symbol Min Typ Max Unit |
