Product Brief
BTS723GW
Smart High-Side Power Switch for 24V Applications, Two Channels 100mΩ
Basic Functions
The BTS723GW is a two channel high-side power switch (two times 100mΩ) in
PG-DSO-14 power package providing embedded protection functions. The device is
„„
CMOS compatible
monolithically integrated in Smart SIPMOS technology. The power transistor is built
„„
Improved electromagnetic
compatibility (EMC)
by N-Channel-planar power MOSFET with a charge pump which boosts the battery
voltage. The inputs are ground referenced CMOS compatible.
„„
Fast demagnetization of
inductive loads
„„
Stable behaviour at undervoltage
„„
Logic ground independent from
load ground
„„
Wide operating voltage range
„„
Optimized inverse current
Applications
