2ch Half-Bridge Gate Driver BD16952EFV-M General Description Key Specifications The BD16952EFV is an AEC-Q100 automotive qualified Input Voltage VS: 5.5V to 40V 2-channel Half-Bridge Gate Driver, controlled by an Input Voltage VCC: 3.0V to 5.5V external MCU through a 16-bit Serial Peripheral Gate Drive Voltage Interface (SPI). Independent control of low-side and 11V(Typ) for Half-Bridge: high-side N-MOSFETS allows for several MCU controlled modes. A programmable drive current is VS Quiescent Supply Current: 0A(Typ) available to adjust slew-rates, in order to meet EMI and VCC Quiescent Supply Current: 2A(Typ) power dissipation requirements. Diagnostics can be Gate Driver Current 1mA to 31mA read and reset by an external MCU. with 1mA step Cross Current Protection Time 0.25s to 92s Features (Note1) AEC-Q100 Qualified SPI clock 7MHz (Max) 2ch Half-Bridge Gate Drivers 4 external MOSFETs are Controlled Independently Package W (Typ) x D (Typ) x H (Max) Half-Bridge Control Modes are Selected by SPI HTSSOP-B24 7.8mm 7.6mm 1.00mm Slew Rates are Controlled with Constant Source /Sink Current. 500 kHz Oscillation for Charge Pump. 16bit SPI (Note1) Grade1 Applications Power window Lifter, Sun Roof Module, Wiper, Seat Belt Tensioner, Seat Positioning etc. Typical Application Circuit VBAT VS C VS VP C CP1 VP CP DRAIN C CP2 CPM T T GH2 GH1 CPP GH1 Voltage SH1 VCC Regulator C VCC GH2 M SI SH2 BD16952EFV T T GL2 GL1 SO GL1 SCLK GL2 C CSB SL RSTB SGND PWM1 PWM2 PGND Product structure: Silicon monolithic integrated circuit This product has no designed protection against radioactive rays. www.rohm.com TSZ02201-0T1T0BD00220-1-2 TSZ02201-0F3F0BD00050-1-2 2016 ROHM Co., Ltd.
