Quad High Side Switch (Dual 10 mOhm, Dual 35 mOhm)

Freescale Semiconductor 

FUNCTIONAL DESCRIPTION

FUNCTIONAL PIN DESCRIPTION

GROUND (GND)

These pins are the ground for the device.

POSITIVE POWER SUPPLY (VPWR)

This pin connects to the positive power supply and is the

source of operational power for the device. The VPWR

contact is the backside surface mount tab of the package.

SERIAL OUTPUT (SO)

The SO data pin is a tri-stateable output from the shift

register. The SO pin remains in a high-impedance state until

the CS pin is put into a logic [0] state. The SO data is capable

of reporting the status of the output, the device configuration,

the state of the key inputs, etc. The SO pin changes state on

the rising edge of SCLK and reads out on the falling edge of

SCLK. SO reporting descriptions are provided in Table 23,

page 39.

HIGH SIDE OUTPUTS (HS3, HS1, HS0, HS2)

Protected 10 mΩ and 12 mΩ high side power outputs to

the load.

FAIL-SAFE INPUT (FSI)

This pin incorporates an active internal pull-up current

source from internal supply (VREG). This enables the

watchdog time-out feature.

When the FSI pin is opened, the Watchdog circuit is

enabled. After a watchdog timeout occurs, the output states

depends on IN[0:3].

When the FSI pin is connected to GND, the watchdog

circuit is disabled. The output states depends on IN[0:3] in

case of VDD Failure condition, in case VDD failure detection

is activated (VDD_FAIL_en bit sets to logic [1]).
