6 / 92 page  Analog Integrated Circuit Device Data 6 Freescale Semiconductor 33911 PIN CONNECTIONS MC33911G5AC/MC3433911G5AC 12 WDCONF Watchdog Configuration Pin This input pin is for configuration of the watchdog period and allows the disabling of the watchdog. 13 LIN LIN Bus This pin represents the single-wire bus transmitter and receiver. 14 LGND LIN Ground Pin This pin is the device LIN ground connection. It is internally connected to the PGND pin. 15,16, 20 & 21 NC Not Connected This pin must not be connected or connected to ground. 17 19 LS2 LS1 Low Side Outputs Relay drivers low side outputs. 18 PGND Power Ground Pin This pin is the device low side ground connection. It is internally connected to the LGND pin. 22 23 L2 L1 Wake-up Inputs These pins are the wake-up capable digital inputs(1). In addition, all Lx inputs can be sensed analog via the analog multiplexer. 24 NC Not Connected This pin must not be connected or connected to VS2. 25 HS1 High Side Output High side switch output. 26 27 VS2 VS1 Power Supply Pin These pins are device battery level power supply pins. VS2 is supplying the HS1 driver while VS1 supplies the remaining blocks.(2) 28 NC Not Connected This pin can be left opening or connected to any potential ground or power supply 29 VSENSE Voltage Sense Pin Battery voltage sense input.(3) 31 VDD Voltage Regulator Output +5.0 V main voltage regulator output pin.(4) 32 AGND Analog Ground Pin This pin is the device analog ground connection. Notes 1. When used as digital input, a series 33 k Ω resistor must be used to protect against automotive transients. 2. Reverse battery protection series diodes must be used externally to protect the internal circuitry. 3. This pin can be connected directly to the battery line for voltage measurements. The pin is self protected against reverse battery connections. It is strongly recommended to connect a 10 k Ω resistor in series with this pin for protection purposes. 4. External capacitor (2.0 µF < C < 100 µF; 0.1 Ω < ESR < 10 Ω) required.
