8 / 37 page  TMC603A DATA SHEET (V. 1.16n / 2016-Apr-08) 8 Copyright © 2009 TRINAMIC Motion Control GmbH & Co. KG Pin Number Type Function VLS 1, 44 Low side driver supply voltage for driving low side gates GNDP 2, 40, 52 Power GND for MOSFET drivers, connect directly to GND VM 3 Motor and MOSFET bridge supply voltage GND 4, 36 Digital and analog low power GND, connect directly to GND RS2G 5 AI 5V Short to GND control resistor. Controls delay time for short to GND test n.c. 6, 7, 8 Do not externally connect these pins (unused outputs) FILTx_ RSx 9, 10, 11 AI 5V AO 5V Output of internal switched capacitor filter or input for external sense resistor (select using pin ENRS_TEST) COSC 12 A 5V Oscillator capacitor for step down regulator TESTCLK 13 DI Test mode input, connect to GND BHx 14, 18, 22 DI 5V High side driver control signal: A positive level switches on the high side BLx 15, 19, 23 DI 5V Low side driver control signal: Polarity can be reversed via INV_BL SAMPLEx 16, 20, 24 DI 5V Optional external control for current measurement sample/hold stage. Set to positive level, if unused CURx 17, 21, 25 AO 5V Output of current measurement amplifier 5VOUT 26 Output of internal 5V linear regulator. Provided for VCC supply n.c. 27 Do not externally connect this pin. VCC 28 +5V supply input for digital I/Os and analog circuitry SENSE_HI 29 DI 5V Switches current amplifiers to high sensitivity BBM_EN 30 DI 5V Enables internal break-before-make circuitry INV_BL 31 DI 5V Allows inversion of BLx input active level (low: BLx is active high) ENABLE 32 DI 5V Enables the power drivers (low: all MOSFETs become actively switched off) /ERR_OUT 33 DO 5V Error output (open drain). Signals undervoltage or overcurrent. Tie to ENABLE for direct self protection of the driver CLR_ERR 34 DI 5V Reset of error flip-flop (active high). Clears error condition RSLP 35 AI 5V Slope control resistor. Sets output current for MOSFET drivers SWOUT 37 O Switch regulator transistor output ENRS_ TEST 38 DI 5V O 12V Enables sense resistor inputs rather than RDSON measurement. Test multiplexer output VCP 39 Charge pump supply voltage. Provides high side driver supply LSx 41, 45, 49 O 12V Low side MOSFET driver output BMx 42, 46, 50 I (VM) Sensing input for bridge outputs. Used for MOSFET control and current measurement. HSx 43, 47, 51 O (VCP) High side MOSFET driver output Exposed die pad - GND Connect the exposed die pad to a GND plane. It is used for cooling of the IC and may either be left open or be connected to GND. |
