| Freescale Semiconductor, Inc. MOTOROLA SEMICONDUCTOR TECHNICAL DATA Document order number: MC33289/D Rev 3.0, 05/2003 Advance Information Dual High-Side Switch The 33289 is a dual high-side switch (DHSS) dedicated for use in automotive and industrial applications. It is designed to drive typical inductive loads such as solenoid valves. This device consists of two independent 40 m RDSON MOSFET channels plus corresponding control circuitry in a surface mount package. The 33289 can be interfaced directly to a microcontroller for input control and monitoring of diagnostic output. 33289 DUAL HIGH-SIDE SWITCH Freescale Semiconductor, Inc... Each switch offers independent protection and diagnosis during short circuit, overvoltage, and undervoltage conditions, as well as an overtemperature shutdown feature. A logic low on the Open Load Detect Enable pin (OLDE) minimizes bias current drain by disabling the open load circuitry current source. The device also has a very low quiescent current in Standby mode.

Pin 1, 2 5, 6 15, 16 19, 20 3, 4 Pin Name VBAT Formal Name Voltage Supply (Battery) Definition These are the power supply pins of the device. These pins are directly connected with the lead frame of the package and are tied to the drain of the switching MOSFET. These pins can be directly connected to the battery voltage. In addition to their supply function, these pins participate to the thermal behavior of the device in conducting the heat from the switching MOSFET to the printed circuit board. These pins are the output one terminals. They connect directly to the source of the power MOSFET. These pins are used by the control circuitry to sense the device output voltage. The RDS(ON) is 40 m maximum per output at 25C and will increase to a maximum of 75 m at 150C junction temperature. These pins do not connect. These are the device input pins. They control their associated outputs. The levels are CMOS compatible. When the input is a logic low, the associated output MOSFET is in the OFF state. When input is high, the MOSFET is turned ON and the load is activated. When both inputs are low, the device is in Standby mode and its supply current is reduced. Each input pin has an internal active pull-down, so it will not float if disconnected. These pins are the channel one fault detection flags. Their internal structure is an open drain architecture with an internal clamp at 6.0 V. An external pull-up resistor connected to VDD (5.0 V) is required. This is an active low output. If the device is in its normal condition the status lines will be high. If open load or other fault occurs, the associated channel status flag will be pulled low. Please see Functional Truth Table. This pin is a digital input, enabling the open load current diagnostic circuitry. When OLDE is a logic low, the open load circuitry is not powered and the bias current draw of the device is at a minimum. If OLDE is a logic high, the open load circuitry is functional at the price of a higher bias current draw. OLDE pin has a pull down resistor. Ground of the integrated circuit. These pins are the channel two fault detection flags. Their internal structure is an open drain architecture with an internal clamp at 6V. An external pull up resistor connected to Vdd (5.0 V) is needed. This is an active low output. If the device is in its normal condition the status lines will be high. If open load or other fault occurs, the associated channel status flag will be pulled low. Please, see Functional Truth Table, Table 1. These are the device input pins. They control their associated outputs. The levels are CMOS compatible. When the input is a logic low, the associated output MOSFET is in the OFF state. When input is high, the MOSFET is turned ON and the load is activated. When both inputs are low, the device is in Standby mode and its supply current is reduced.

DEVICE DESCRIPTION INTRODUCTION The 33289 is a dual high-side switch with appropriate control, protection, and diagnostic features dedicated to drive inductive loads such as solenoid drivers for automotive and industrial applications. The device consists of two independent applications with two independent 40 m power switches. It can be linked directly with a microcontroller. It is available in a SOICW 20 surface mount package. Each output has a 40 m RDSON maximum 25C. The RDSON value reaches 75 m at 150C junction temperature. Each output has a parasitic drain to source diode, inherent to any vertical MOSFET. This diode can sustain as much current at the MOSFET. The diode is reversed biased during normal operation of the MOSFET and is forward biased during reverse battery, or negative transient pulses. Power Supply Status The device has an independent status pin per output, reporting an overtemperature, overcurrent, and an open load condition in the device. This pin is an open drain structure, requiring an external pull-up resistor. The device incorporates overtemperature sense on each output MOSFET in order to independently protect each output. Freescale Semiconductor, Inc... The 33289 can be directly connected to the supply line. In Standby mode (in-1 and in-2 at 0V), the supply current is less than 5.0 A for VBAT supply voltage below 14 V. This feature allows a very low supply current on the battery, for example, when an auto is idle or parked. During OFF state, the status pins are in high impedance. In case of loss of (digital) ground, the power MOSFETs turn OFF in order to safely tie the load current to zero. Open Load Function The open load detection is active during the OFF phase, or cold open load detection. An amplifier measures the differential voltage between VBAT and VOUT. When the load current is below 400 mA, the open load circuitry will pull down the status output. The open load circuitry can be disabled with the OLDE to ensure very low standby current. Nominal Voltage and Transient Operation The nominal operation voltage is from 6.0 to 26 V. The 33289 device is functional over a larger voltage range from 6.0 V to 27V. The technology used for both power and analog circuitry sustains 40 V DC voltage. Power Output Switches The device has two independent high-side switches. Each switch is realized with an N-channel power MOSFET and includes current and temperature sensing circuitries. The MOSFET gates are driven by analog circuitry which includes charge pump and fault detection. Package The device is assembled into a surface mount package. 33289 8 For More Information On This Product, Go to: www.freescale.com MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA Freescale Semiconductor, Inc.
