4 / 60 page  Analog Integrated Circuit Device Data 4 Freescale Semiconductor 16XSD200 PIN ASSIGNMENT PIN ASSIGNMENT Figure 3. Device Pin Assignments Table 1. 16XSD200 Pin Description The function of each pin is described in the section Functional Description Pin Number Pin Name Function Formal Name Definition 1 CSNS Output Output Current/ Temperature Monitoring This pin either outputs a current proportional to the channel’s output current or a voltage proportional to the temperature of the GND pin (pin 14). Selection between current and temperature sensing, as well as setting the current sensing sensitivity are performed through the SPI interface. An external pull- down resistor must be connected between CSNS and GND. 2 3 IN0 IN1 Input Direct Inputs The IN[0:1] input pins are used to directly control the switching state of both switches and consequently the voltage on the HS0:HS1 output pins. The pins are connected to GND by internal pull-down resistors 4 FSOB Output Fail-safe Output (Active Low) FSOB is asserted (active-low) upon entering Fail-safe mode (see Functional Description) This open-drain output requires an external pull-up resistor to VPWR 5 6 CONF0 CONF1 Input Configuration Input The CONF[0:1] input pins are used to select the appropriate overcurrent detection profile (bulb/DC motor) for each of both channels. CONF requires a pull-down resistor to GND. 7 FSB Output Fault Status (Active Low) This open-drain output pin (external pull-up resistor to VDD required) is set when the device enters Fault mode (see Fault Mode) 8 CLOCK Input PWM Clock The clock input gives the time-base when the device is operated in external clock/internal PWM mode. This pin has an internal pull-down current source. 9 RSTB Input Reset This input pin is used to initialize the device’s configuration - and fault registers. Reset puts the device in Sleep mode (low current consumption) provided it is not stimulated by direct input signals.This pin is connected to GND by an internal pull-down resistor. 10 CSB Input Chip Select (Active Low) This input pin is connected to the SPI chip-select output of an external micro- controller. CSB is internally pulled up to VDD by a current source IUP. Transparent Top View 20 19 15 14 HS0 HS1 GND VPWR 23 22 21 16 17 18 SYNC GND VPWR SO GND VPWR 16XSD200 |
