APPLICATION GUIDELINES

General

Unused DRN

inputs should be connected to V

CC1

prevent false open load faults. Unused parallel inputs

should be connected to GND and unused enable inputs

should be connected to V

CC1

. The mask bit for each unused

channel should be ‘set’ (see Table 5) to prevent activation

of the flags and the user’s software should be designed to

ignore fault information for unused channels. For best

shorted−load detection accuracy, the external MOSFET

source terminals should be star−connected and the

NCV7513’s GND pin, and the lower resistor in the fault

reference voltage divider should be Kelvin connected to

the star (see Figures 2 and 13).

Consideration of auto−retry fault recovery behavior is

necessary from a power dissipation viewpoint (for both the

NCV7513 and the MOSFETs) and also from an EMI

viewpoint.

Driver slew rate and turn−on/off symmetry can be

adjusted externally to the NCV7513 in each channel’s gate

circuit by the use of series resistors for slew control, or

resistors and diodes for symmetry. Any benefit of EMI

reduction by this method comes at the expense of increased

switching losses in the MOSFETs.

The channel fault blanking timers must be considered

when choosing external components (MOSFETs, slew

control resistors, etc.) to avoid false faults. Component

choices must ensure that gate circuit charge/discharge

times stay within the turn−on/turn−off blanking times.

The NCV7513 does not have integral drain−gate flyback

clamps. Clamp MOSFETs, such as ON Semiconductor’s

NID9N05CL, are recommended when driving unclamped

inductive loads. This flexibility allows choice of MOSFET

clamp voltages suitable to each application.

DRN

Feedback Resistor

Each DRN

feedback input has a clamp to keep the

applied voltage below the breakdown voltage of the

NCV7513. An external series resistor (R

) is required

between each DRN

input and MOSFET drain. Channels

may be clamped sequentially or simultaneously but total

clamp power is limited to the maximum allowable junction

temperature.

To limit power in the DRN

input clamps and to ensure

proper open load or short to GND detection, the R

resistor must be dimensioned according to the following

constraint equations:

DX(MIN)

−V

CL(MIN)

CL(MAX)

(eq. 2)

DX(MAX)

−

(eq. 3)

where V

is the peak transient drain voltage, V

is the

DRN

input clamp voltage, I

CL(MAX)

is the input clamp

current, and V

and I

are the respective short to GND

fault detection voltage and diagnostic current, and V

the allowable offset (1.0 V max) between the NCV7513’s

GND and the short.

Once R

is chosen, the open load and short to GND

detection resistances in the application can be predicted:

Using the data sheet values for V

CL(MIN)

= 27 V,

CL(MAX)

= 10 mA, and choosing V

= 55 V as an

example, Equation 2 evaluates to 2.8 kW minimum.

values for V

Equation 5 predicts a short to GND detection resistance of

and the data sheet values are taken to

their extremes, the open load detection range is 94.1 kW v

v 273.5 kW, and the short to GND detection range is

59.2 W v R

v 84.4 W.
