Load Switching Capabilities and Characteristics

On-state resistance (pin 3 to 5)

IL = 2 A, Vbb = 24 V

Tj=25 °C: RON

Tj=150 °C:

Nominal load current, ISO Norm (pin 3 to 5)

VON = 0.5 V, TC = 85 °C

Output current (pin 5) while GND disconnected or

GND pulled up, Vbb=32 V, VIN= 0, see diagram

page 7

Turn-on time to 90% VOUT:

Turn-off time to 10% VOUT:

RL = 12 Ω, Vbb = 20V, Tj =-40...+150°C

Slew rate on, 10 to 30% VOUT,

RL = 12 Ω, Vbb = 20V, Tj =-40...+150°C

Slew rate off, 10 to 30% VOUT,

RL = 12 Ω, Vbb = 20V, Tj =-40...+150°C
