UPD16835

MONOLITHIC QUAD H BRIDGE DRIVER CIRCUIT

NEC => Renesas Technology 

µPD16835

Remark The meanings of the symbols listed in Table 5-4 are as follows:

ENABLE : Output setting (H : Conducts, L : Stops)

ROTATION : Rotation direction (H : Reverse (CCW), L : Forward (CW))

PULSEOUT : Output pulse signal

FF7 : Presence/absence of pulse in LATCH cycle (Outputs H level if output pulse information exists in

standard data.)

FF3 : Pulse gate (output while pulse exists)

FF2 : Outputs H level during start up wait time + start up drive wait time

FF1 : Outputs H level during start up wait time

CHECKSUM : Checksum output (H : when normal data is transmitted,

L : when abnormal data is transmitted)

CHOPPING : Chopping wave output (in original oscillation mode only)

<6th byte>

The 6th byte sets the peak output current value of α ch. The output current is determined by the EVR reference

voltage.

The 250-mV (TYP.) voltage input from an external source to the VREF pin is internally doubled and input to a 4-bit

D/A converter. By dividing this voltage by 4-bit data, an EVR reference voltage can be set inside the IC within the

range of 200 to 500 mV, in units of 20 mV.

The µPD16835 can set two values of the EVR reference voltage in advance. This is done by using bits D0 to D3 or

D4 to D7. Which of the two EVR reference voltage values is to be used is specified by the CURRENT SET bit in the

standard data.

If all the bits of the 6th byte are “0”, the EVR reference voltage of 200 mV is selected; if they are “1”, the EVR

reference voltage of 500 mV is selected.

<7th byte>

The 7th byte specifies the peak output current value of β ch. The output current is determined by the EVR reference

voltage.

The 250-mV (TYP.) voltage input from an external source to the VREF pin is internally doubled and input to a 4-bit

D/A converter. By dividing this voltage by 4-bit data, an EVR reference voltage can be set inside the IC within a range

of 200 to 500 mV, in units of 20 mV.

The µPD16835 can set two values of the EVR reference voltage in advance. This is done using bits D0 to D3 or D4

to D7. Which of the two EVR reference voltage values is to be used is specified by the CURRENT SET bit in the

standard data.

If all the bits of the 7th byte are “0”, the EVR reference voltage of 200 mV is selected; if they are “1”, the EVR

reference voltage of 500 mV is selected.
