Pin name
Hall element bias current pin.
Goes ON when the S/S pin is in a start state.
Goes OFF when the S/S pin is in an stopped state.
Hall amplifier input pin.
A high level state of logic is recognized when IN + > IN − .
In reverse case is a low-level state.
The input amplitude of 100mVp-p or more (differential) is
desirable in the Hall sensor inputs.
If noise on the Hall inputs is a problem, that noise must be
excluded by inserting capacitors across the inputs.
Frame ground pin. This pin is connected with the GND2 pin.
Ground pin of the output circuit block.
Output pin.
As for PWM, Duty control is executed on the upper- side
FET.
Source pin of output MOSFET (lower-side).
Connect a low resistance (Rf) between this pin and GND.
Output current detection pin.
Connect to RF pin.
Power supply pin.
Connect a capacitor between this pin and GND for
stabilization.
Power supply pin for control.
Charge pump output pin (Power supply for the upper side
FET gate).
Connect a capacitor between this pin and V CC .
Pin to connect a capacitor for charge pump.
Connect a capacitor between CP1 and CP2.
