8.2.1.1 Design Requirements

When selecting the gate driver device for an end application, some design considerations must be evaluated in order to make the most appropriate selection. Following are some of the design parameters that should be used when selecting the gate driver device for an end application: input-to-output configuration, the input threshold type, bias supply voltage levels, peak source and sink currents, availability of independent enable and disable functions, propagation delay, power dissipation, and package type. See the example design parameters and requirements in Table 8-1.

Table 8-1 Design Parameters

DESIGN PARAMETER	EXAMPLE VALUE
Input to output logic	Non-inverting
Input threshold type	TTL
Bias supply voltage levels	+18 V
Negative output low voltage	N/A
dV_DS/dt⁽¹⁾	100 V/ns
Enable function	Yes
Disable function	N/A
Propagation delay	<30 ns
Power dissipation	<1 W
Package type	SON8 or SOIC8

(1) dV_DS/dt is a typical requirement for a given design. This value can be used to find the peak source/sink currents needed as shown in Section 8.2.1.2.4.
