RDS(on) 160 m
Iout 0.7 A
VCC 45 V
CMOS compatible input Junction over-temperature protection Case over-temperature protection for thermal independence of the channels Current limitation Shorted load protection Undervoltage shutdown Protection against loss of ground Very low stand-by current Compliance to 61000-4-4 IEC test up to 4 kV
PowerSO-36
It can be driven by using a 3.3 V logic supply. Active current limitation combined with thermal shutdown and automatic restart, protect the device against overload. In overload condition, channel turns OFF and back ON automatically so as to maintain junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, overloaded channel is turned OFF and will restart only when case temperature has decreased down to TCR(see waveform 3 Figure 6 on page 10). Non overloaded channels continue to operate normally. Device automatically turns OFF in case of ground pin disconnection. This device is especially suitable for industrial applications conform to IEC 61131.

Reverse polarity protection

Reverse polarity protection
A schematic solution to protect the IC against a reverse polarity condition is proposed. This schematic is effective with any type of load connected to the outputs of the IC. The RGND resistor value can be selected according to the following conditions to be met: 1. 2. RGND 600 mV / (IS in ON state max). RGND (-VCC) / (-IGND)
where -IGND is the DC reverse ground pin current and can be found in the absolute maximum rating section of the device datasheet. The power dissipation associated to RGNG during reverse polarity condition is: PD = (-VCC)2/RGND This resistor can be shared by several different ICs. In such case IS value on formula (1) is the sum of the maximum ON-state currents of the different devices. Please note that if the microprocessor ground and the device ground are separated then the voltage drop across the RGND (given by IS in ON state max * RGND) produce a difference between the generated input level and the IC input signal level. This voltage drop will vary depending on how many devices are ON in the case of several high side switches sharing the same RGND. Figure 8. Reverse polarity protection
