●Description

of pins and cautions on layout of board

1) VCC1 (Input-side power supply pin)

The VCC1 pin is a power supply pin on the input side. To suppress voltage fluctuations due to the current to drive

internal transformers, connect a bypass capacitor between the VCC1 and the GND1 pins.

2) GND1 (Input-side ground pin)

The GND1 pin is a ground pin on the input side.

3) VCC2 (Output-side positive power supply pin)

The VCC2 pin is a positive power supply pin on the output side. To reduce voltage fluctuations due to OUT1 pin output

current and due to the current to drive internal transformers, connect a bypass capacitor between the VCC2 and the

GND2 pins.

4) VEE2 (Output-side negative power supply pin)

The VEE2 pin is a power supply pin on the output side. To suppress voltage fluctuations due to OUT1 pin output current and

due to the current to drive internal transformers, connect a bypass capacitor between the VEE2 and the GND2 pins. To use

no negative power supply, connect the VEE2 pin to the GND2 pin.

5) GND2 (Output-side ground pin)

The GND2 pin is a ground pin on the output side. Connect the GND2 pin to the emitter / source of a power device.

6) IN (Control input terminal)

The IN pin is a pin used to determine output logic.

INB

INA

OUT1

7) FLT (Fault output pin)

The FLT pin is an open drain pin used to output a fault signal when a fault occurs (i.e., when the undervoltage lockout

function (UVLO), short current protection function (SCP) or thermal protection function is activated).

This pin is I/O pin and if L voltage is externally input, the output is set to L status regardless of other input logic.

Consequently, be sure to connect the pull-up resistor between VCC1 pin and the FLT pin even if this pin is not used.

When an Fault occurs

(When UVLO, SCP or thermal protection is activated)

8) FLTRLS (Fault output holding time setting pin)

The FLTRLS pin is a pin used to make setting of time to hold a Fault signal. Connect a capacitor between the FLTRLS

pin and the GND1 pin, and a resistor between it and the VCC1 pin.

The Fault signal is held until the FLTRLS pin voltage exceeds a voltage set with the V

FLTRLS

parameter. To set holding

time to 0 ms, do not connect the capacitor. Short-circuiting the FLTRLS pin to the VCC1 pin will cause a high current to

flow in the FLTRLS pin and, in an open state, may cause the IC to malfunction. To avoid such trouble, be sure to connect

a resistor between the FLTRLS and the VCC1 pins.

9) OUT1 (Output pin)

The OUT1 pin is a pin used to drive the gate of a power device.

10) OUT2 (MOS FET control pin for Miller Clamp)

The OUT2 pin is a pin for controlling the external MOS switch for preventing increase in gate voltage due to the miller

current of the power device connected to OUT1 pin.

11) VREG (Power supply pin for driving MOS FET for Miller Clamp)

The VREG pin is a power supply pin for driving MOS FET for Miller Clamp. Be sure to connect a capacitor between

VREG pin and VEE2 pin for preventing the oscillation and to reduce voltage fluctuations due to OUT2 pin output current.

12) PROOUT (Soft turn-off pin)

The PROOUT pin is a pin used to put the soft turn-off function of a power devise in operation when the SCP function is

activated. This pin combines with the gate voltage monitoring pin for Miller Clamp.

13) SCPIN (Short current detection pin)

The SCPIN pin is a pin used to detect current for short current protection. When the SCPIN pin voltage exceeds a

voltage set with the V

SCDET

parameter, the SCP function will be activated. This may cause the IC to malfunction in an

open state. To avoid such trouble, short-circuit the SCPIN pin to the GND2 pin if the short current protection is not used.

In order to prevent the wrong detection due to noise, the noise mask time t

SCPMSK

is set.
