ELECTRICAL CHARACTERISTICS (continued)

Table 13. Current Sense (9V<VCC<16V)

Note:(*) Analog sense current drift is deviation of factor K for a given device over (-40°C to 150°C and 9V<VCC<16V) with respect to it’s

value measured at Tj=25°C, VCC=13V.

WAVEFORMS AND TRUTH TABLE

Table 14. Truth Table In Normal Operating Conditions

In normal operating conditions the DIAGX/ENX pin is

considered as an input pin by the device. This pin must be

externally pulled high.

PWM pin usage: in all cases, a “0” on the PWM pin will

turn-off both LSA and LSB switches. When PWM rises

back to “1”, LSA or LSB turn on again depending on the

input pin state.
