Document Number: MC33289 Rev. 4.0, 6/2006
Dual High-Side Switch 40 m
The 33289 is a Dual High Side Switch (DHSS) dedicated for use in automotive 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. Each switch offers independent protection and diagnosis during overcurrent, 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.

Figure 2. 33289 Pin Connections Table 1. Pin Function Description
Pin Number 1, 2, 5, 6, 15, 16, 19, 20 Pin Name VBAT Pin Function Supply Voltage 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. Pins 3 and 4 are the output 1 pins. Pins 17 and 18 are the output 2 pins. They are directly connected to the source of the power MOSFET. These pins are used by the control circuitry to sense the device output voltage. The RDSON is 40 m max per output at 25C and will increase to a maximum of 75 m at 150C junction temperature. These are the device input pins which directly 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 that it will not float if disconnected. 9, 12 ST1 ST2 Status for Channel 1 Status for Channel 2 These pins are the channel 1 and channel 2 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 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. See Functional Truth Table. This pin is a digital input which enables the open load current diagnostic circuitry. When OLDE is a logic low, the open load circuitry is not powered and the device's bias current draw 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. This is the GND pin of the device.
