... BD62321HFP Overview BD62321HFP is full bridge driver for brush motor applications. This IC can operate at a wide range of power-supply voltages (from 6V to 32V), supporting output currents 3A. MOS transistors in the output stage allow for PWM signal control. The replacement is also easy because of the pin compatible with BD623XHFP series. ...

... BD62321HFP Functional descriptions 1) Operation modes FIN RIN PWM PWM * Hi-Z is the off state of all output transistors. Please note that this is the state of the connected diodes, which differs from that of the mechanical relay. a) Stand-by mode In stand-by mode, all internal circuits are turned off, including the output power transistors. Motor output goes to high impedance ...

... BD62321HFP e) f) PWM control mode The rotational speed of the motor can be controlled by the switching duty when the PWM signal is input to the FIN pin or the RIN pin. In this mode, the high side output is fixed and the low side output does the switching, corresponding to the input signal. The switching operates by the output state toggling between " ...

... BD62321HFP c) Thermal shutdown (TSD) circuit The TSD circuit operates when the junction temperature of the driver exceeds the preset temperature (175°C nominal). At this time, the controller forces all driver outputs to high impedance. Since thermal hysteresis is provided in the TSD circuit, the chip returns to normal operation when the junction temperature falls below the preset temperature (150° ...
