 1 configurable high-side driver for up to 1.5 A
(R_ON = 500 mΩ) or 0.35 A (R_ON = 1600 mΩ)
load
 1 configurable high-side driver for 0.8 A
(R_ON = 800 mΩ) or 0.35 A (R_ON = 1600 mΩ)
load
 3 configurable high-side drivers for
0.15 A/0.35 A (R_ON =2 Ω)
 1 configurable high-side driver for 0.25 A/0.5 A
(R_ON = 2 Ω)
 4 configurable high-side drivers for
0.15 A/0.25 A (R_ON = 5 Ω)
 Internal 10bit PWM timer for each stand-alone
high-side driver
 Buffered supply for voltage regulators and 2
high-side drivers (OUT15 & OUT_HS / both 
P-channel) to supply e.g. external contacts
 Programmable soft-start function to drive loads
with higher inrush currents as current limitation
value (for OUT1-6, OUT7, OUT8 and
OUT_HS) with thermal expiration feature
 All the embedded outputs come with protection
and supervision features:
– Current Monitor (high-side only)
– Open-load
Datasheet - production data
– Overcurrent
– Thermal warning
– Thermal shutdown
 Fully protected driver for external MOSFETs in
H-bridge configuration
 Two 5 V voltage regulators for microcontroller
and peripheral supply
 Programmable reset generator for power-on
and undervoltage
 Configurable window watchdog
 LIN 2.2a compliant (SAEJ2602 compatible)
transceiver
 Separated (Isolated) fail-safe block with 2 LS
(R_ON = 1 Ω) to pull down the gates of the
external HS MOSFETs
 Thermal clusters
 A/D conversion of supply voltages and internal
temperature sensors
 Embedded and programmable VS duty cycle
adjustment for LED driver outputs
