ABSOLUTE MAXIMUM RATINGS
Supply Voltage (VCC) DC................................................................-0.3V to 5.5V
Supply Voltage (VCC) Transient .........................................................-0.3V to 6V
Driver Supply Voltage (VCCL) DC .....................................................-0.3V to 13V
Driver Supply Voltage (VCCL) Transient............................................-0.3V to 16V
Driver Supply Voltage (VC1) DC .......................................................-0.3V to 19V
Input Voltage (SS/DIS) .....................................................................-0.3V to 5.5V
Output Drive Peak Current Source (HO, LO).......................................1A (500ns)
Output Drive Peak Current Sink (HO, LO) ..........................................1A (500ns)
Operating Temperature Range .........................................................-40
°C to 85°C
Maximum Operating Junction Temperature ................................................ 150
°C
Storage Temperature Range...........................................................-65
°C to 150°C
Lead Temperature (Soldering 180 seconds) ................................................ 235
°C
Package Peak Temp. for Solder Reflow (40 Seconds Maximum Exposure).. 255°C(+5, -0)
Note: Exceeding these ratings could cause damage to the device. All voltages are with respect to
Ground. Currents are positive into, negative out of specified terminal
.
The limitation on transient time is thermal and is due to zener diodes on the supply
pins, application of maximum voltages will increase current into that pin and
increase package power dissipation.
