Product Brief
BTS 5246-2L
Smart High-Side Power Switch
Two Channels 19 mΩ
T H E B T S 5 2 4 6 - 2 L is a dual channel high-side power switch
(two channels, 19 mΩ) in PG-DSO-12 power package providing embedded protective
functions. Integrated resistors at each input pin (IN1, IN2, CLA) reduce external
components.
The load current limitation can be adjusted in two steps by the current limit adjust
pin (CLA). The IntelliSense pins IS1 and IS2 provide a sophisticated diagnostic
feedback signal including current sense function, open load in OFF-state and short
circuit protection.
The power transistor is built by a N-channel vertical power MOSFET with charge
pump. The inputs are ground referenced CMOS compatible. The device is
monolithically integrated in Smart SIPMOS technology.
