Using a Shunt Resistor to Dissipate Energy
... R pp is the phase-to-phase resistance of the motor, I Q is the current at brake time. The additional power Pshunt = P − Pmot needs to be dissipated on the shunt resistor. Otherwise, the bus voltage Vbus will rise and may cause damage to the bus components that cannot withstand the high voltage level ...

Difet OPA627 OPA637 Precision High-Speed
... Difet fabrication of the OPA627/637 provides very low input bias current. Since the gate current of a FET doubles approximately every 10°C, to achieve lowest input bias current, the die temperature should be kept as low as possible. The high speed and therefore higher quiescent current of the OPA627 ...
