Automotive Power

Short-circuit protection

TOPFET applications of high-side switches

Designed to meet the demands of the harsh automotive

environment, Philips’ TOPFETs integrate a wide array of

sophisticated control and protection measures into highly

robust devices.They offer a uniquely simple design-in process

for protected PowerMOS applications.

S e m i c o n d u c t o r s

Philips’ BUK2xx-50Y single-channel TOPFET family of 50V high-side switches

offers an extensive range of safety features including protection against short

circuits. Depending on the severity of the short circuit, the devices respond

in one of two ways: a very rapid latched short-circuit trip or a slower

thermal over-temperature protection.

Latched short-circuit protection

A latched short-circuit trip will occur when both the following conditions

are met:

1. The time elapsed since switch-on is greater than the parameter t_dsc

Typically t_dsc= 180 µs.

2. The battery-load voltage,V_BL, is greater than the trip threshold voltage,

V_BL(to), which is approximately two-thirds of the battery-ground voltage,

V_BG. In this case, the device is actively limiting the load current to some

value I_L(lim)

Under the above circumstances, the device latches OFF and stays latched

OFF until the input is toggled low and then high again, or the battery supply

is removed and replaced. As an example we use the following typical values:

V_BG= 16V, V_BL(to)= 10V and I_L(lim)= 18 A.Then the maximum load

resistance that will trip the short-circuit detector is

Key features

• No external components required as protection is fully integrated

within the TOPFET

• Integrated R_Gfor reverse battery and supply transients protection

• Very low power dissipation due to low on-state resistance

• Very low quiescent current

R_L= (V_BG–V_BL(to)) / I_L= (16 – 10) / 18 = 0.333 Ω

• Diagnostic status indicator

• Virtually undetectable charge pump noise

A load resistance lower than R_Lwill be viewed as a short circuit and cause

the device to switch off. If this short circuit occurs at a time greater than

t_dscafter switch-on (short circuit while already ON) the device will be

tripped within a few microseconds. However, if the short circuit is already

present at switch-on (turn-on into short circuit) the device will only trip

after a delay equal to t_dsc.This delay ensures there is no unwanted tripping

during device turn on.

Key benefits

• Input and status circuits see past the internal R_Gand refer their levels

to true ground

• Low EMC emissions

Key applications

• 12 and 24V grounded loads

• High in-rush current loads

• Inductive loads

Thermal protection

In a ‘soft’ short circuit there is a gentler overload in which one of the

above conditions is not met and hence the latched short-circuit detector

• Replacements for relays and fuses
